Best 350cc–500cc Bikes in India: Royal Enfield, Triumph & Mid-Capacity Classics

Quick answer: For relaxed classic riding, the Royal Enfield Classic 350 or Honda H'ness CB350. For outright performance, the KTM 390 Duke (in its higher-output "R" form). For touring on rough Indian roads, the Royal Enfield Himalayan 450.

There isn't really a mainstream 500cc new one to buy. Royal Enfield's old 500cc singles (Classic 500, Bullet 500, Thunderbird 500) were discontinued years ago and never got a BS6-compliant replacement.

This guide covers three types of bikes modern classics, performance roadsters, and adventure/scrambler between 349cc–452cc motorcycles, plus a tax-driven engine downsizing wave that hit several of these bikes in 2026 and changed what "400" actually means on a badge.

Hero Mavrick 440 is not in this table because it's been discontinued. It was part of earlier "modern classic" comparisons, but Hero quietly pulled it from sale in mid-2025 after sales fell to single digits a month.

All prices are approximate and gathered in September 2026 - several of these figures changed meaningfully earlier this year (details below), and they'll keep moving. Confirm the current figure with the manufacturer before buying.

Royal Enfield's classic 500cc singles never made the jump to BS6 emissions norms and were discontinued years ago. Since then, the 350–450cc band has absorbed nearly all the buyer intent that used to go toward "a proper 500cc single" — enough torque and road presence for a satisfying ride, without the cost and complexity of a genuine 500cc-plus machine.

Nothing in this guide is a literal 500cc motorcycle; "350cc–500cc" describes the search intent and buyer decision this page serves, not a literal displacement claim about every model in it.

Effective 22 September 2025, India's GST 2.0 reform created a sharp tax cliff for motorcycles: 18% GST for engines up to 350cc, versus 40% GST for anything above it — a jump from the previous, much gentler 28–31% band. That's a large enough gap to change a purchase price by tens of thousands of rupees, and it triggered a wave of engine downsizing across brands that share ownership or manufacturing with Bajaj Auto.

Triumph moved first, relaunching its entire India range — Speed 400, Scrambler 400 X, Scrambler 400 XC, Thruxton 400 and a new Tracker 400 — on 6 April 2026 with a smaller 349cc engine (achieved by shortening the stroke from 64mm to 56.1mm while keeping the same 89mm bore), while keeping the "400" name on every model. Power dropped from roughly 40 PS to the mid-30s PS range, depending on the specific model's state of tune.

Bajaj followed with the Dominar 400, relaunched around 12–16 April 2026 with the same downsizing approach: displacement cut from 373.3cc to 349.13cc, power essentially unchanged at 40.4–40.6 PS but torque down from 35 Nm to 33.2 Nm, and — notably — a genuine price cut of about ₹37,000. The Pulsar NS400Z got the identical 349.13cc engine around 21 April 2026, with similar output, though Bajaj initially kept the price essentially unchanged rather than passing on the tax saving.

KTM followed in April 2026 too, but handled it differently: rather than simply downsizing the 390 Duke and 390 Adventure, KTM now sells both a standard 349cc version (41–41.5 PS) at a lower price, and keeps the original 399cc engine's higher output (45–46 PS) available in a separate, pricier variant now marketed as the "390 Duke R" for buyers who specifically want the pre-downsizing performance.

Royal Enfield took the opposite approach. Its 440–450cc models — Himalayan 450, Guerrilla 450 and Scram 440 — kept their original 451.65cc engine unchanged and simply absorbed the new 40% GST slab, which pushed prices up by roughly 7.3% (about ₹15,000–22,000 depending on model and variant) rather than changing the engine.

Why this matters for you?

If you're reading an older comparison, a road test, or even this article's own approved research pack, any Speed 400, Scrambler 400X, Dominar 400, Pulsar NS400Z or 390 Duke performance figure dated before April 2026 describes an engine that Indian buyers can no longer actually buy new. The badge still says "400" or "390," but the engine inside several of these bikes is now genuinely smaller than it used to be.

Given the above, displacement badges in this class are now a weaker signal than they used to be — treat the number on the tank as a starting point for research, not a reliable spec. What actually separates these bikes:

• Long-stroke, torque-focused engines (Royal Enfield Classic 350, Honda H'ness CB350, Harley-Davidson X440): relaxed, low-RPM power delivery that prioritises tractability over outright speed.

• Oversquare, higher-output engines (Triumph Speed 400, KTM 390 Duke, Bajaj Pulsar NS400Z, in both their pre- and post-downsizing forms): built to rev harder for stronger acceleration, at some cost to low-end tractability.

• Royal Enfield's near-square "Sherpa" 452cc architecture (Himalayan 450, Guerrilla 450): deliberately balanced between the two philosophies, rather than leaning hard into either one.

The instrumented 0–100 km/h figures below come from the pre-2026 versions of these bikes — before the GST-driven downsizing described above. Where a bike has since been re-engined with less power, expect these times to be slower today, and treat the ranges as historical reference rather than a current guarantee.

Royal Enfield Classic 350

This one remains the default choice for relaxed, upright classic riding, and it undercuts the Honda CB350 on price at every trim level. Its base "Redditch" variant uses single-channel ABS and a standard wet multiplate clutch; every variant above it adds dual-channel ABS and an assist-and-slipper clutch that lightens the lever pull.

Honda H'ness CB350

It shares a broadly similar engine character with the Classic 350 but is a lighter, nimbler machine with a notably more effortless clutch action. Its taller gearing suits the highway better than stop-start city riding, and it holds a genuine mileage edge over the Classic 350 as a result.

Harley-Davidson X440

This model steps up in both displacement and price: its 440cc engine gives it meaningfully stronger performance than the air-cooled 350s, with the trade-off of correspondingly lower fuel economy. It's the most expensive bike in this category, and the only one with genuine Harley-Davidson badge value in India.

A note on the Hero Mavrick 440:
This was the fourth bike in this category and the most affordable of the 440cc trio, sharing its platform with the X440. It's been discontinued — Hero pulled it from sale in mid-2025 after sales collapsed to single digits a month, reportedly due to styling that departed too far from what modern-classic buyers wanted. If you're specifically hunting for one, expect to buy used, not new.

Triumph Speed 400

The most city-friendly of this trio's original lineup, tuned for tractable, everyday riding rather than outright thrills — though its now-349cc engine (since April 2026) has given up some of the top-end punch it launched with.

KTM 390 Duke

The enthusiast's pick, and since April 2026 it comes in two forms: the standard 349cc version at a lower price, and the "390 Duke R" retaining the original, higher-output 399cc engine for buyers who specifically want the performance the Duke was originally known for. If outright thrills are your priority, confirm which version you're being quoted before you commit.

Bajaj Pulsar NS400Z

This one is the value performance pick in this group, now sharing its downsized 349.13cc engine with the Dominar 400. It remains a usable daily bike with genuine highway entertainment on tap, at a price well below the Triumph or KTM.

Royal Enfield Himalayan 450

Strongest all-rounder for genuinely rough Indian roads: a liquid-cooled DOHC engine, 200mm of suspension travel front and rear, and 230mm of ground clearance, all wrapped in a package built specifically for touring rather than commuting. Its price climbed meaningfully in late 2025 when Royal Enfield chose to absorb the new 40% GST rate rather than downsize the engine, so it's no longer the value option it once was — but the hardware underneath is unchanged.

Royal Enfield Guerrilla 450

Shares the Himalayan's engine in a roadster body, trading some off-road capability for a lighter, more road-focused package. It's a genuine alternative to the performance roadsters above if you want the 452cc engine's mid-range character without the ADV styling or the Himalayan's higher price.

Triumph Scrambler 400X

This model brings scrambler styling — a 19-inch front wheel and generous suspension travel for light off-road use — but like its Speed 400 sibling, it now runs the downsized 349cc engine as of April 2026, with a measurable step back in acceleration versus the bike's original launch spec.

Benelli TRK 502

This one sits above this entire comparison as a premium, parallel-twin alternative rather than a mainstream pick — worth knowing exists if your budget stretches further, but not a direct value comparison against anything else on this page.

The long-stroke classics (Classic 350, H'ness CB350, X440) settle into a genuinely relaxed cruise around 80–90 km/h, with the H'ness's taller gearing giving it a slight edge in reduced highway stress despite a similar low-end character to the Classic 350.

The performance roadsters and the Himalayan/Guerrilla pair can sustain higher cruising speeds with more overtaking reserve in hand, at the cost of a buzzier feel at the very top of that range — road-test and owner observations specifically note this vibration pattern on the Himalayan 450, Speed 400 and Dominar 400 at sustained high-speed cruising, though the exact sensation is inherently subjective and varies by rider.

Suspension, Ground Clearance and Broken-Road Ability

The Himalayan 450 is purpose-built for this: 200mm of travel at both ends and 230mm of ground clearance put it well ahead of everything else in this guide for genuinely rough terrain. The Scrambler 400X, with 150mm of travel and 195mm of clearance, is a capable step down from the Himalayan for light trail use rather than serious off-roading.

The classics and performance roadsters are tuned for sealed roads — usable on moderately broken surfaces, but not built for the same abuse the Himalayan is designed to take.

Royal Enfield's Himalayan and Guerrilla platforms have the most mature official accessory ecosystem in this group, reflecting their touring-first design brief — official panniers, top boxes and crash protection are widely available through Royal Enfield's own accessory catalogue and dealer network.

The Bajaj and Triumph performance roadsters have a smaller factory accessory range by comparison, with the Dominar 400 specifically marketed with a factory touring kit as an option. Confirm current accessory availability and pricing directly with each manufacturer, since these ranges change without much notice.

Pillion Comfort and Two-Up Touring

The Royal Enfield Himalayan 450 and Classic 350 are generally regarded as the most pillion-friendly bikes here, with genuinely usable rear seats and a riding position that doesn't put a passenger in an awkward crouch.

The performance roadsters (Speed 400, 390 Duke, NS400Z) are usable two-up for shorter rides but aren't built around passenger comfort the way the Royal Enfield pair is.

The Guerrilla 450's more compact roadster proportions make it slightly less spacious for a pillion than its Himalayan sibling.

Real-world mileage across this class runs meaningfully below any ARAI-claimed figure you'll see advertised — treat the ranges below as observed, not guaranteed:

Across the whole class, expect somewhere in the region of 24–32 km/l in the city and 30–42 km/l on the highway depending on the specific model and how it's ridden — these figures predate the 2026 engine downsizing for the affected models, and a smaller, lower-output engine would generally be expected to return somewhat better mileage than its predecessor.

A simple running-cost example: at ₹100/litre and 30 km/l (a reasonable mid-pack highway figure for this class), covering 10,000 km a year costs roughly ₹33,333 in fuel — about ₹2,778 a month. Swap in your own actual mileage and local fuel price for a number that means something for your situation; this is a methodology to reuse, not a fixed answer for every bike here.

• Relaxed classic riding, tightest budget: Royal Enfield Classic 350, the most affordable entry point into the whole category.

• Relaxed classic riding, better mileage: Honda H'ness CB350, a genuine step up in fuel economy and refinement for a modest price premium.

• Outright performance: KTM 390 Duke, specifically the "390 Duke R" if you want the pre-downsizing power output.

• Value performance roadster: Bajaj Pulsar NS400Z, the most affordable way into this power bracket.

• Serious touring and rough roads: Royal Enfield Himalayan 450, built for the job, priced accordingly after its 2025 GST-driven increase.

• Road-focused alternative to the Himalayan: Royal Enfield Guerrilla 450, the same engine, a lighter and more street-oriented package.

• Distinctive styling on a mid-size budget: Harley-Davidson X440, the most premium badge in this comparison at a genuinely accessible price.
