Guerrilla 450 vs Speed 400 vs X440 vs Mavrick 440: The Ultimate 2026 Modern Retro Roadster Comparison

Royal Enfield’s grip on India’s 250cc-plus motorcycle market has slipped from over 90% to roughly 75% in a few short years, according to industry estimates — and the clearest evidence of why is this four-way fight. Royal Enfield Guerrilla 450 vs Triumph Speed 400 vs Harley-Davidson X440 has become one of the most-searched motorcycle comparisons in India in 2026, and the Hero Mavrick 440 — built on the same platform as the X440 — completes what was meant to be a genuine four-way contest for the same buyer’s wallet. All four are single-cylinder, accessible, retro-styled roadsters priced within roughly ₹2-2.8 lakh ex-showroom, which means the decision usually comes down to power, features, brand trust, and running costs rather than raw affordability. In this guide, we compare official pricing, verified specifications, real owner feedback, and running costs across all four bikes, reconcile the handful of places where sources disagree, and — unlike most comparisons on this topic — flag the Mavrick 440’s current discontinued status and end with buyer-specific recommendations instead of a single forced “winner.”

Royal Enfield Guerrilla 450 vs Triumph Speed 400 vs Harley-Davidson X440: Why These Four Bikes Are Competing for the Same Buyer

For nearly two decades, if you wanted an accessible, single-cylinder retro-styled motorcycle in India above the 250cc mark, there was really only one badge worth considering: Royal Enfield. That is no longer true. Royal Enfield Guerrilla 450 vs Triumph Speed 400 vs Harley-Davidson X440 is now one of the most searched comparisons among Indian bike buyers, and the reason is structural, not just enthusiast chatter — Bajaj’s tie-up with Triumph and Hero MotoCorp’s tie-up with Harley-Davidson have both landed direct, similarly-priced challengers squarely inside Royal Enfield’s home turf. Industry estimates put Royal Enfield’s share of the 250cc-plus segment at over 90% just a few years ago; several trade reports now peg it closer to 75%, with Triumph and Harley-Davidson’s budget sub-brands accounting for most of the erosion.

All four motorcycles in this comparison — the Royal Enfield Guerrilla 450, Triumph Speed 400, Harley-Davidson X440, and Hero Mavrick 440 — are pitched as accessible, single-cylinder retro roadsters in a tight ₹2-2.8 lakh ex-showroom band. Each targets a slightly different kind of buyer: outright performance, badge prestige, relaxed cruiser character, or value.

One important update before we go further: as of this writing (July 2026), Hero MotoCorp has effectively discontinued the Mavrick 440. Multiple trade reports (RideApart, Visordown, AckoDrive) note that production and dispatches quietly stopped months ago, dealers have stopped taking fresh bookings, and Hero has not listed the model prominently on its official site for some time. Hero has not issued a formal discontinuation statement, so we’re treating this as strongly-evidenced but not 100% officially confirmed. We’re keeping the Mavrick 440 in this comparison because (a) it remains relevant to anyone shopping the used/dealer-stock market, and (b) understanding why it lost out to its own platform-sibling, the X440, is genuinely useful context for buyers choosing between the other three.

Price & Variants Compared

Ex-showroom pricing for all four changed meaningfully after the GST 2.0 rate revision took effect on 22 September 2025, which pushed the tax on motorcycles above 350cc from 28% (plus 3% cess) up to a flat 40%. Every bike here except the Mavrick 440 (which was already exiting the market) saw list prices move in response. All prices below are ex-showroom Delhi, as of July 2026.

Two things stand out. First, the Royal Enfield Guerrilla 450’s 2026 model-year update (launched 27 March 2026) dropped the entry-level Analogue variant and added a road-focused Apex trim with Vredestein Centauro ST tyres and a more forward-leaning riding posture — so the cheapest way into a Guerrilla 450 today is the Dash, not an Analogue. Second, even at its last listed pricing, the Mavrick 440 undercut every rival here by a meaningful margin, which makes its commercial failure — reportedly around 3,214 units sold in FY2025 against roughly 8,974 units for the mechanically similar X440 — a genuinely interesting data point about how much badge and dealer network matter in this segment over sheer value. If you’re weighing the Hunter 350 as an even more affordable Royal Enfield alternative, that same badge-versus-value dynamic applies.

Engine & Performance Compared

Engine character is the single biggest differentiator in the Royal Enfield Guerrilla 450 vs Triumph Speed 400 vs Harley-Davidson X440 match-up, and it’s where the four bikes split cleanly into two camps: liquid-cooled performance engines (Guerrilla 450, Speed 400) and air/oil-cooled, torque-focused engines (X440, Mavrick 440).

A quick note on data reconciliation, since we’d rather flag this than quietly pick a number: some spec sheets list the Guerrilla 450’s output as 40.02 PS rather than a flat 40 PS. Royal Enfield’s own India press material rounds this to 40 PS, so that’s the figure we’ve used throughout. On the Speed 400, we re-verified directly against Triumph’s own official India specification page at the time of this revision, and it currently lists the engine as 349.0cc, producing 37 PS @ 8,500rpm and 32 Nm @ 7,000rpm — cross-checked and matched against BikeWale and ICICI Lombard’s bike-spec listings. This is lower than the 398.15cc / 40 PS / 37.5 Nm figure that has circulated widely across Indian auto publications and aggregator sites (and was used in an earlier version of this article, incorrectly, based on a misread of the same official page). We can’t fully explain why the two figures differ — it may reflect a running spec change Triumph has made since launch — but because 349cc/37PS/32Nm is what Triumph’s own current page shows, that is the figure we’re using here. If you see 398.15cc quoted elsewhere, treat it as outdated pending Triumph clarifying the change, and always check the official page for the latest number before you buy.

In real terms: with the corrected figures, the Guerrilla 450 is now clearly the most powerful and quickest of the four, with a meaningful edge over the Speed 400 in both outright power (40 PS vs 37 PS) and low-end torque (40 Nm vs 32 Nm) — this is a different picture from what earlier spec sheets suggested. The Speed 400 still comfortably out-performs the X440 and Mavrick 440 on paper and remains the revviest-feeling engine of the four relative to its size, but it’s no longer a near-match for the Guerrilla at the top end. The X440 and Mavrick 440 trade outright numbers for a lazier, more relaxed power delivery — Team-BHP owner reports describe both as staying refined and unstressed right up to around 110 km/h, after which they feel noticeably out of their comfort zone on the highway.

Chassis, Suspension & Handling

The Speed 400 and X440 both get 43mm upside-down front forks — a genuinely premium touch at this price point — while the Guerrilla 450 uses conventional telescopic forks with a twin-downtube spine frame, and the Mavrick 440 rides on a trellis frame with twin-shock rear suspension (shared conceptually with the X440’s rear end, though tuned differently). Braking hardware favours the American-badged pair: the X440 and Mavrick 440 both get a 320mm front disc, the largest here, while the Guerrilla 450 counters with the largest rear disc at 270mm. All four get dual-channel ABS as standard.

On the road, this translates into two distinct handling characters. Owners and reviewers consistently describe the Guerrilla 450 and Speed 400 as the sportier, more flickable bikes of the group — sharper steering, better front-end feedback, and more composure if you actually push on a ghat road. The X440 and Mavrick 440 are tuned for a more relaxed, cruiser-adjacent riding experience: stable in a straight line, less eager to change direction quickly, and happiest at a steady cruising pace rather than being hustled through corners.

Features & Technology

The Guerrilla 450 is comfortably the most tech-loaded bike here. The Dash and Flash variants get a 4-inch round TFT display with Google Maps turn-by-turn navigation built in, plus two riding modes (Performance and Eco), ride-by-wire, and a USB-C port. The Speed 400, by contrast, is the odd one out on tech — it sticks to a semi-digital instrument console with no built-in navigation, though it does uniquely offer switchable traction control among these four. The X440 gets a 3.5-inch circular TFT on its S and T variants with Bluetooth-based navigation and call alerts, and the range-topping T adds ride-by-wire, two riding modes, and traction control. The Mavrick 440 used a digital LCD console with turn-by-turn navigation and smartphone connectivity — reasonably well equipped for what was the segment’s value option, though it lacked a full-colour TFT.

If feature richness and a modern dash matter to you more than outright badge, the Guerrilla 450 is the clear pick — and if you want to see how Royal Enfield is pushing tech even further, its Flying Flea C6 electric platform shows where the brand’s dashboard and connectivity tech is headed next.

Dimensions, Ergonomics & Comfort

*Mavrick 440 seat height and wheelbase figures vary slightly between third-party listings and were not independently confirmed on an official Hero page at the time of writing, given the model’s discontinued status — treat these as close approximations rather than exact factory specification.

The Guerrilla 450 is the most approachable for shorter riders, combining the lowest seat height with the longest wheelbase for stability. The X440 is the tallest and, per Team-BHP owner threads, also the heaviest to muscle around at a standstill — something to factor in if you’re under 5’6″.

Fuel Efficiency & Running Costs

This is the one area where none of the competitor comparisons we cross-checked give a complete, apples-to-apples picture across all four bikes — so we’re being explicit about what’s confirmed versus estimated. Royal Enfield’s own materials suggest a Guerrilla 450 mileage figure in the high-20s kmpl range; Team-BHP owner logs report a wide spread from 21 kmpl (heavy city use) up to 30-34 kmpl on the highway ridden gently — noticeably below the claimed figure for city riders. The Speed 400’s claimed mileage sits around 30 kmpl, and real-world owner logs on Team-BHP have reported figures as high as 33.5 kmpl on a mixed run, suggesting Triumph’s claim is realistic for most riders. Harley-Davidson quotes roughly 35 kmpl for the X440, though we could not find a large enough sample of independently-verified owner logs to confirm this in everyday use — treat it as a claimed figure pending more real-world data. The Mavrick 440’s ARAI-rated figure was 35 kmpl, though owner-reported test runs on Rushlane and forum threads put real-world figures closer to 31-38 kmpl depending on conditions.

On running costs, network size matters as much as service pricing. Royal Enfield’s dealer and service network in India dwarfs the other three combined, which matters for parts availability and turnaround time — especially relevant now that Mavrick 440 owners may face longer waits for parts given the model’s discontinued status. Triumph (via Bajaj’s showroom network) and Harley-Davidson (via Hero’s) have both expanded meaningfully in the last two years, but neither yet matches Royal Enfield’s reach into smaller towns.

Which One Should You Buy? Verdict by Rider Type

There’s no single “winner” in the Royal Enfield Guerrilla 450 vs Triumph Speed 400 vs Harley-Davidson X440 debate — and any comparison that hands you one is skipping the part where these four bikes actually appeal to different people.

If you want the most power, the most features, and the most confidence-inspiring highway manners, the Royal Enfield Guerrilla 450 is the easiest recommendation. It has the biggest engine, the most usable torque spread, the best display and navigation tech, and Royal Enfield’s unmatched service network behind it — the Flash variant at ₹2.72 lakh is expensive for the segment, but the Dash at ₹2.49 lakh undercuts the top X440 T comfortably while out-powering it.

If fit-and-finish, engine refinement, and a genuine British performance pedigree matter most, the Triumph Speed 400 is the pick. Owners consistently praise build quality that “punches above its price bracket,” and it’s the only bike here with switchable traction control — though you sacrifice navigation and a colour TFT to get it.

If you want a relaxed, torquey cruiser feel and don’t mind the American badge premium, the Harley-Davidson X440 — especially the mid-spec S variant — makes sense, provided you’re comfortable with a taller seat and can look past scattered owner reports of early electronics glitches and hot-weather starting issues that a handful of Team-BHP members have flagged. Our full breakdown of Harley’s India range is worth a read if you’re brand-curious: see our Harley-Davidson India lineup guide.

As for the Hero Mavrick 440 — it was, on paper, the best-value bike of the four, undercutting everything else here by a wide margin at launch. But its effective discontinuation tells its own story: Indian buyers in this segment overwhelmingly chose badge and dealer confidence over a slightly cheaper price tag from a brand without an established big-bike identity. If you find genuine, unsold dealer stock, it can still be a smart buy purely on numbers — just go in aware that resale and long-term parts support are real question marks. We’ve tracked this bike’s journey before in our Hero Mavrick 440 Scrambler coverage, and for buyers exploring Hero’s other 2026 options, our Hero Karizma XMR 250 preview is a useful next read.

Frequently Asked Questions

Which of these four has the best resale value?
The Royal Enfield Guerrilla 450 is expected to hold resale value best, purely on the strength of Royal Enfield’s brand history, dealer network, and consistently strong used-bike demand in India. The Speed 400 should also hold up reasonably well given Triumph’s growing India presence; the X440’s resale is still an unknown given how new the platform is, and the Mavrick 440’s discontinuation will likely hurt its resale value the most.

Which is cheapest to maintain?
On paper, the Mavrick 440 and X440 have mechanically simpler air/oil-cooled engines that are typically cheaper to service than liquid-cooled units. In practice, Royal Enfield’s dense, low-cost service network usually keeps the Guerrilla 450’s real-world running costs competitive, or even lower, despite the more complex engine.

Which is fastest?
The Royal Enfield Guerrilla 450 is the fastest of the four on paper, making 40 PS and 40 Nm — the most power and torque here by a clear margin. Triumph’s own official specification page confirms the Speed 400 makes 37 PS and 32 Nm from a 349cc engine (not the 398.15cc/40PS figure sometimes quoted elsewhere), putting it second. The X440 and Mavrick 440, at roughly 27-27.4 PS, are noticeably slower in a straight line and are tuned for relaxed cruising rather than outright pace.

Is the Hero Mavrick 440 as good as the Harley-Davidson X440 it’s related to?
Mechanically, yes — both share the same 440cc platform, similar power and torque figures, and comparable running gear. The X440 differentiates itself with the Harley badge, a broader variant spread (Vivid, S, T) with more premium electronics on the top trim, and Hero’s much larger service network behind the Harley brand in India, which likely explains why the X440 has significantly outsold the Mavrick 440.

Which has the best warranty?
The Triumph Speed 400 comes with a 2-year, unlimited-mileage warranty from Bajaj-Triumph. Royal Enfield, Harley-Davidson (via Hero), and Hero MotoCorp all offer broadly comparable 2-3 year warranty terms with optional extended coverage; check current terms with your dealer, as these are revised periodically.

Is the Hero Mavrick 440 still available to buy new in India?
Largely, no. Multiple 2025-26 trade reports indicate Hero MotoCorp has quietly halted production and dispatch of the Mavrick 440, and dealers are no longer taking fresh bookings in most markets. Hero has not issued an official discontinuation statement, so treat this as strongly-evidenced but unofficial — existing dealer stock may still be available in some cities.
