The Royal Enfield Guerrilla 450 strips away the adventure pretense of its Himalayan sibling to deliver a pure roadster experience with the proven 452cc Sherpa engine. After three weeks of city commutes, highway runs, and spirited twisty-road sessions, we’ve gathered real-world data on performance, mileage, and the ownership experience that matters beyond the spec sheet. Here’s everything you need to know before booking one.
Quick Verdict: The Guerrilla 450 nails the balance between modern performance (40PS/40Nm) and classic Royal Enfield character, delivering quicker acceleration than the Speed 400 (6.57s vs 7.49s to 100kmph) and better real-world fuel economy (29kmpl vs 26kmpl). It’s 11kg lighter than the Himalayan, more city-friendly, and packed with ride modes and TFT connectivity on upper variants. Trade-offs include a small 11-liter tank limiting range to ~300km, firmer suspension that can feel jarring on bad roads, and a slightly heavy clutch in stop-go traffic. Best for: Urban riders who want torque-rich midrange punch, neo-retro style, and modern tech without the bulk of an ADV not for mileage chasers or comfort-first tourers.

Engine & Performance
Sherpa 452cc Heart
The Guerrilla borrows the Himalayan’s liquid-cooled, DOHC, 4-valve single making 40.02PS at 8,000rpm and 40Nm at 5,500rpm. Royal Enfield tuned it for roadster duty with a 45-tooth rear sprocket (vs 47T on Himalayan) for snappier acceleration. The engine management system includes ride-by-wire throttle, Eco and Performance modes, and a slip-assist clutch.
Real-World Acceleration
In back-to-back drag tests, the Guerrilla hit 100kmph in 6.57 seconds, nearly a full second quicker than the Triumph Speed 400’s 7.49s. The 0-60kmph sprint takes just 2.87 seconds, making traffic overtakes confident and decisive. The broader midrange torque curve (livelier between 3,000-6,000rpm) gives the Guerrilla a useful punch in low-speed maneuvers compared to the Speed 400’s narrower power-band.
Top Speed & Highway Cruising
Top speed sits around 140kmph per manufacturer claims, with comfortable cruising at 100-120kmph. Some vibrations emerge past 6,000rpm and become more prominent above 8,000rpm, though less viby than the Himalayan. The 6-speed gearbox holds highway speeds easily, though the engine makes little torque below 2,500rpm, requiring more frequent shifts in crawling traffic.
City vs Highway Character
City: Exciting acceleration and compact proportions make the Guerrilla slick in traffic, though the slightly heavy clutch and low-end torque dip (under 2,500rpm) can frustrate in stop-go conditions. Once rolling above 4,000rpm, it feels in its element.
Highway: The 185kg wet weight and long wheelbase deliver planted stability at speed, even in crosswinds or wet conditions. Owner feedback confirms “confident overtakes” and “solid high-speed stability” on open roads.
Mileage & Fuel Economy
ARAI vs Real-World Numbers
Royal Enfield claims 29.5kmpl ARAI. In mixed riding conditions (city, highway, spirited twisties), the Guerrilla returned 29.08kmpl remarkably close to the claim. By comparison, the Speed 400 delivered 26.25kmpl in identical tests, making the Guerrilla more fuel-efficient despite similar power.
Tank Range Reality
The compact 11-liter fuel tank (6 liters smaller than Himalayan’s 17L) limits range to approximately 300-320km on a full tank. The Speed 400’s 13-liter tank extends its range to 341km despite worse economy, a 21km advantage that matters on long tours. Owners report 25-28kmpl in city commutes and 30-34kmpl on highways with sane riding.
Cost Per Kilometer
At current fuel prices (~₹100/liter) and 29kmpl average, you’re spending roughly ₹3.45 per km. Over 10,000km annually, expect ₹34,500 in fuel costs competitive for the 450cc class.
Design & Build Quality
Neo-Retro Roadster Aesthetic
The Guerrilla blends Hunter 350’s round LED headlight and fork gaiters with a sleeker tank featuring an offset fuel cap, creating what one tester called “a bike that looks like it entered a custom competition”. The rear section mirrors the Himalayan 450 with the same exhaust and taillight-integrated turn indicators.
Color & Variant Options
Three variants span ₹2.39-2.54 lakh ex-showroom (now ₹2.56-2.72L post-GST 2.0):
- Analogue: Smoke Silver (semi-digital cluster from Super Meteor 650)
- Dash: Playa Black, Gold Dip, Peix Bronze (4″ TFT + Bluetooth)
- Flash: Brava Blue, Yellow Ribbon (4″ TFT + Bluetooth)
Standout colors include Brava Blue’s color-matched subframe and front wheel, and the bold Yellow Ribbon for maximum road presence.
Build Quality & Fit-Finish
Solid construction catches attention everywhere, with good panel gaps and quality materials. The 160-section rear tire is the widest in its segment, adding to the muscular stance. Minor quibbles: some owners dislike the rotary dial switchgear on new RE models.
Features & Technology
Instrument Console Options
Flash/Dash variants: 4-inch circular TFT with Bluetooth connectivity, Google Maps turn-by-turn navigation, media controls, and multiple ride modes. The screen auto-switches between light/dark themes based on ambient light, though visibility suffers under harsh sunlight due to reflections.
Analogue variant: Semi-digital cluster with analogue speedometer and digital inset, plus optional Tripper navigation pod.
Rider Aids & Safety
- Dual-channel ABS (non-switchable)
- Ride-by-wire throttle with Eco and Performance modes
- Engine kill switch, side stand indicator, hazard lights
- USB Type-C charging port
- Full LED lighting (headlight, taillight, turn signals, DRLs)
- Gear indicator, service due indicator, distance-to-empty
Missing: Traction control, though testers noted it wasn’t necessary even in monsoon conditions.
Connectivity & Smartphone Integration
Bluetooth pairing enables call/SMS alerts, music controls, and phone-based navigation mirroring on the TFT. Geo-fencing and vehicle location tracking add security layers.
Ride Comfort & Ergonomics
Seating Position
Upright, neutral riding posture with a low 780mm seat height accommodates shorter riders and provides commanding visibility. The single-piece seat feels firm on rides over 2 hours, prompting some owners to add aftermarket cushions.
Suspension Setup
Front: 43mm conventional telescopic forks (non-adjustable), 140mm travel
Rear: Linkage-type monoshock (preload-adjustable), 150mm travel
The suspension is tuned firm for sporty handling, absorbing small bumps decently but feeling jarring over potholes or undulations at speed. Owners describe it as “slightly firm but not harsh” in cities, “composed on bumpy village roads,” and “stable in twisties”. Highway riders appreciate the planted feel, though some report rear bounce on really bad patches.
Weight & Maneuverability
At 185kg kerb weight, the Guerrilla feels light and nimble in traffic, easy to maneuver in tight spots despite not being as flickable as the 176kg Speed 400. The long 1,440mm wheelbase and fat tires (120/70 front, 160/60 rear) favor high-speed stability over quick direction changes.
Handling & Braking
Corner Stability vs Agility
The Guerrilla doesn’t match the Speed 400’s sharp, sporty agility you need to put in slightly more effort to tip it into corners or flick side-to-side. However, once committed to a line, it holds it with impressive stability. The CEAT block-pattern tires (more form than function) perform well in the dry but don’t inspire confidence on wet roads.
Brake Performance
310mm front and 270mm rear discs deliver decent initial bite and stable, confident stops. The front brake has adequate power for the class; the rear brake is less aggressive but gets the job done. No reported issues with brake fade or ABS intervention during spirited riding.

The Bottom Line
The Royal Enfield Guerrilla 450 carves a unique space as a torque-rich, tech-forward roadster that doesn’t pretend to be practical. It beats the Speed 400 in straight-line acceleration and fuel economy while delivering more emotional engagement than the numbers suggest. The Sherpa 452cc engine proves versatile, the neo-retro styling polarizes but turns heads, and the modern features (TFT, Bluetooth, ride modes) finally bring RE into 2025.
Trade-offs are honest: the small tank demands frequent stops, the firm suspension won’t pamper on broken roads, and the weight doesn’t vanish in tight corners. But for urban riders craving a characterful, powerful daily rider with weekend adventure potential without the bulk of an ADV or the sterility of a sportbike the Guerrilla 450 hits a sweet spot few competitors reach.
At ₹2.56-2.72 lakh, it asks a premium over the Speed 400, but you’re buying into Royal Enfield’s expanding modern lineup with the service network to back it. If your rides rarely exceed 250km per leg and you value torque over absolute refinement, this is the roadster that finally makes the “new Royal Enfield” promise real.
Frequently Asked Questions
Is the Royal Enfield Guerrilla 450 worth buying in 2025?
Yes, if you prioritize torque-rich performance (40Nm), modern features (TFT, Bluetooth, ride modes), and neo-retro style over absolute comfort or touring range. It accelerates quicker than the Speed 400 (6.57s vs 7.49s to 100kmph) and delivers better real-world mileage (29kmpl vs 26kmpl), making it a strong choice for urban and weekend riders. However, the small 11L tank (~300km range) and firm suspension may deter long-distance tourers or comfort-first buyers.
What is the real-world mileage of the Guerrilla 450?
In mixed riding conditions (city, highway, spirited twisties), the Guerrilla 450 returned 29.08kmpl, remarkably close to the 29.5kmpl ARAI claim. Owners report 22-28kmpl in city commutes and 30-35kmpl on highways with sane riding. With the 11-liter tank, expect approximately 300-320km range per fill-up.
How does the Guerrilla 450 compare to the Triumph Speed 400?
The Guerrilla is quicker (6.57s vs 7.49s to 100kmph), more fuel-efficient (29kmpl vs 26kmpl), and packs more tech (TFT, Bluetooth, ride modes). The Speed 400 is lighter (176kg vs 185kg), more agile, cheaper (₹2.34L vs ₹2.56L), and more refined. Choose the Guerrilla for torque, character, and modern features; pick the Speed 400 for nimbleness, refinement, and value.
What are the main problems with the Guerrilla 450?
Owners report four recurring concerns: (1) small 11L fuel tank limiting range to 250-300km, (2) firm rear suspension feeling jarring on bad roads, (3) seat firmness causing discomfort after 2+ hours, and (4) heat buildup in slow traffic, though it dissipates quickly when moving. The slightly heavy clutch can frustrate in stop-go traffic.
Which variant of the Guerrilla 450 should I buy?
The Dash variant (₹2.67L ex-showroom) offers the best value, adding the 4-inch TFT with Bluetooth and navigation for just ₹11k over the base Analogue. The Flash (₹2.72L) only adds different colors (Brava Blue, Yellow Ribbon) for ₹5k more worthwhile only if those shades appeal. Skip the Analogue unless the budget is tight; the TFT dramatically improves usability.
Is the Guerrilla 450 good for long rides?
It’s capable but not ideal. The 40PS/40Nm engine cruises comfortably at 100-120kmph, and owners report successful 600+ km trips. However, the 11-liter tank requires fuel stops every 250-300km, the firm seat causes discomfort after 2 hours, and the stiff suspension can be taxing on bad highways. For occasional 200-300km weekend rides, it’s fine; for serious touring, the Himalayan 450’s 17L tank and softer suspension are better.
What is the top speed of the Royal Enfield Guerrilla 450?
The Guerrilla 450 has a claimed top speed of 140kmph per official specifications. Some sources estimate it could reach approximately 170kmph under optimal conditions, though vibrations become prominent above 8,000rpm. Comfortable highway cruising sits at 100-120kmph with stable, planted handling.
How much does the Guerrilla 450 cost on-road?
On-road prices (including registration, insurance, taxes) range from ₹2.94 lakh in Ahmedabad to ₹3.32 lakh in Bangalore for the base Analogue variant. Ex-showroom pricing post-GST 2.0 (September 2025) starts at ₹2,56,387 (Analogue), ₹2,67,116 (Dash), and ₹2,72,479 (Flash). Prices vary by state; check with local dealers for accurate quotes.
