It's a 124.7 cc air-cooled single, fuel-injected and BS6 Phase 2B compliant. The tuning prioritises low-to-midrange responsiveness over pure top-end performance: maximum torque arrives at 6,500 rpm, which means useful pull is available at typical city riding revs of 3,000-5,000 rpm. The top 2026 variant adds Electronic Throttle Body (ride-by-wire), enabling three ride modes - Eco, Road, and Power - and electronic cruise control, both firsts in the sporty 125cc category. ### Braking - Segment's Largest Front Disc The 276mm front disc is the biggest in the 125cc commuter segment. Larger disc diameter increases mechanical advantage, improving initial bite and heat dissipation during repeated hard braking. For context: TVS Raider 125 and Honda SP 125 use 240mm front discs. The difference is felt in city stop-start riding - the Xtreme 125R stops with noticeably more confidence. ### Segment Spec Comparison | Spec | Hero Xtreme 125R | TVS Raider 125 | Honda SP 125 | |---|---|---|---| | Engine | 124.7 cc | 124.8 cc | 123.9 cc | | Power | 11.4 bhp | 11.38 PS | 10.7 bhp | | Torque | 10.5 Nm | 11.2 Nm | 11 Nm | | ARAI Mileage | 66 kmpl | 65.44 kmpl | 60 kmpl | | Kerb Weight | 136 kg | 123 kg | 130 kg | | Front Disc | 276mm | 240mm | 240mm | | Seat Height | 795 mm | 800 mm | 790 mm | ## Brakes & Wheels | Spec | Value | |------|-------| | Braking System | IBS | | Front Brake | Disc, 240 mm, 2 piston caliper | | Rear Brake | Drum, 130 mm | | Tyre Pressure (Rider & Pillion) | Front - 27 psi, Rear - 29 psi | | Tyre Pressure (Rider Only) | Front - 27 psi, Rear - 29 psi | | Tyre Size | Front - 90/90 - 17, Rear - 120/80 - 17 | | Tyre Type | Tubeless | | Wheel Size | Front - 17 inch, Rear - 17 inch | | Wheel Type | Alloy | ## Dimensions | Spec | Value | |------|-------| | Fuel Tank Capacity | 10 litres | | Ground Clearance | 180 mm | | Kerb Weight | 136 kg | | Overall Dimensions (LxWxH) | 2009 mm x 793 mm x 1051 mm | | Reserve Fuel Capacity | 1.6 litres | | Seat Height | 794 mm | | Wheelbase | 1319 mm | ## Power & Performance | Spec | Value | |------|-------| | Battery | MF12V, 4Ah | | Bore x Stroke | 52.4 mm x 57.8 mm | | Clutch | Wet Multiplate | | Compression Ratio | 9.9:1 | | Displacement | 124.7 cc | | Emission Standard | BS6 Phase 2B | | Engine Type | 1 Cylinder, Air Cooled, 2 Valves | | Fuel Type | Petrol | | Gear Shifting Pattern | 1 Down 4 Up | | Max Power | 11.4 bhp @ 8250 rpm | | Max Torque | 10.5 Nm @ 6000 rpm | | Mileage - ARAI | 66 kmpl | | Mileage - Owner Reported | 57 kmpl | | Riding Modes | No | | Riding Range | 660 km | | Spark Plugs | 1 Per Cylinder | | Top Speed | 100 kmph | | Transmission | 5 Speed Manual | | Transmission Type | Chain Drive | ## Suspensions & Chassis | Spec | Value | |------|-------| | Chassis Type | Diamond Frame | | Front Suspension | Dia. 37 Telescopic Fork | | Front Suspension Preload Adjuster | No | | Rear Suspension | Rectangular Swingarm with 7 Step Preload Adjustable Monoshock | | Rear Suspension Preload Adjuster | Yes | ## Warranty and Services | Spec | Value | |------|-------| | 1st Service | 500-750 km or 60 days | | 2nd Service | 3000-3500 km or 160 days | | 3rd Service | 6000-6500 km or 260 days | | 4th Service | 9000-9500 km or 360 days | | 5th Service | 12000-12500 km or 460 days | | No. of Free Services | 5 | | Vehicle Warranty | 70,000 km or 5 years | ### Suspension and Tyres The Xtreme 125R runs conventional telescopic forks at the front and a monoshock at the rear - the monoshock is a step up from the twin-shock setup found on rivals like the Honda SP 125, contributing to a more composed ride over broken urban roads. The 120/80-17 rear tyre is wider than the 100/70-17 rear used by many 125cc rivals, giving a slightly larger contact patch and more planted feel in corners. At 136 kg, the Xtreme 125R is heavier than the TVS Raider 125 (123 kg), though the weight is evenly distributed and the bike doesn't feel unwieldy in traffic. ### Ground Clearance & Dimensions Ground clearance is 168mm - adequate for typical Indian road conditions including speed breakers and potholed urban stretches. The 795mm seat height keeps the bike accessible for most riders above 5'4". ## FAQs **What engine does the Hero Xtreme 125R have?** The Hero Xtreme 125R is powered by a 124.7 cc air-cooled, single-cylinder, fuel-injected engine branded 'SPRINT'. It produces 11.4 bhp at 8,250 rpm and 10.5 Nm of torque at 6,500 rpm. The top 2026 variant adds ride-by-wire (Electronic Throttle Body) which enables three ride modes and electronic cruise control. **What is the fuel efficiency of the Hero Xtreme 125R?** The ARAI-certified mileage is 66 kmpl. In real-world city use, owners report 53-60 kmpl; on open highways the figure rises to 60-65 kmpl. The top variant's Eco ride mode helps extract better fuel efficiency in city traffic. The 10-litre tank gives a practical range of approximately 530-600 km per fill. **What suspension setup does the Hero Xtreme 125R use?** The Hero Xtreme 125R uses conventional telescopic forks at the front and a monoshock at the rear. The monoshock rear is a premium setup for the 125cc segment - most rivals in this price range use twin-shock rear suspension. It provides better bump absorption over city potholes and a more composed highway ride. **What is the front brake disc size on the Hero Xtreme 125R?** The Hero Xtreme 125R has a 276mm front disc brake - the largest front disc in the 125cc commuter segment in India. For comparison, the TVS Raider 125 and Honda SP 125 use 240mm front discs. The larger rotor provides stronger initial braking bite and better heat dissipation in city stop-start riding. **What is the kerb weight of Hero Xtreme 125R?** The Hero Xtreme 125R weighs 136 kg kerb weight. It is heavier than the TVS Raider 125 (123 kg) but lighter than the Yamaha FZ-S FI (149 kg). The extra weight versus the Raider is generally not felt in regular city riding but may require a little more effort when parking or manoeuvring in tight spaces. ## More - [Overview](/bikes/hero/xtreme-125r) - [Variants & Prices](/bikes/hero/xtreme-125r/variants) - [Price in India](/bikes/hero/xtreme-125r/price)
