About the Triumph Bonneville T120

Overview

The Triumph Bonneville T120 is a cafe racer motorcycle from Triumph. It is currently on sale. Café racers take their look from 1960s British racers: a low handlebar, a slim tank and minimal bodywork. With a 1,200 cc engine it sits in the big-bike, 800 cc-plus class.

Engine and performance

Power comes from a 1,200 cc twin-cylinder liquid-cooled engine that makes 78.9 bhp at 6,550 rpm and 105 Nm of torque at 3,500 rpm. Peak torque arrives low in the rev range, at 3,500 rpm, which makes it relaxed to ride in traffic. Its bore is wider than its stroke (97.6 mm x 80 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 339 PS per tonne; by that measure, it is genuinely fast, well beyond everyday traffic speeds. The claimed top speed is 190 km/h. It has electric start.

Gearbox

It has a 6-speed manual gearbox with a 1-down, 5-up shift pattern, and a chain carries drive to the rear wheel. It uses a wet multi-plate clutch.

Chassis, brakes and tyres

Its frame is tubular steel, with twin cradles. Suspension is by Ø41 mm cartridge forks at the front and twin RSU’s, with pre-load adjustment rear suspension at the rear. Braking is by a disc at the front and a disc at the rear, with dual-channel ABS. ABS on both wheels keeps either tyre from locking under hard braking. It rides on 18-inch front and 17-inch rear spoke wheels — 100/90 - 18 at the front and 150/70 - R17 at the rear.

Size, comfort and range

The seat is 790 mm off the ground, which is about average and suits most riders. It weighs 236 kg ready to ride, which is heavy, so parking and tight U-turns need care. Ground clearance is 140 mm — adequate, though tall speed breakers need care. It is 2,120 mm long, with 1,450 mm between the axles. Its 14.5 L fuel tank and claimed mileage of 21-22.2 kmpl work out to roughly 322 km per tankful on paper; real-world range is usually lower.

Features and equipment

Equipment includes a semi-digital instrument console, an LED headlamp, USB charging port, distance-to-empty readout, gear position indicator, service due indicator, shift light, engine temperature indicator, low fuel indicator and low oil indicator. Safety equipment includes engine kill switch, side-stand engine cut-off, hazard light switch, traction control and malfunction indicator. It has a rain and Road riding mode.

Warranty terms: Unlimited km or 2 years. For the Triumph Bonneville T120, Mechiee offers a fixed ₹9,999 doorstep service.

Who it suits

It is best suited to riders who want retro style as much as performance. With this much performance, it is better as a step-up bike than a first bike.

Care notes for this model

Recommended tyre pressures are 32 psi front and 36 psi rear, solo or with a pillion. Its chain drive needs regular cleaning, lubrication and slack adjustment.

Maintaining the Triumph Bonneville T120

  • Routine servicing

    Follow the schedule in the owner's manual for your exact variant and year. A regular service is the cheapest way to catch small problems before they become expensive ones.

  • Engine oil & filter

    Engine oil is the single most important consumable to keep fresh. Top up between services if the level drops, and change it on schedule.

  • Brake inspection

    With Disc and Disc brakes, check pad or shoe wear, lever and pedal free play, and braking feel at every service.

  • Chain cleaning & lubrication

    A clean, correctly tensioned and lubricated chain lasts longer and wastes less power. Check slack regularly, especially after riding in rain or dust.

  • Coolant & cooling system

    A liquid-cooled engine relies on coolant. Check the level and look over hoses and the radiator for leaks or damage, and replace coolant as the owner's manual directs.

  • Air filter & spark plug

    A clogged air filter or worn spark plug shows up as hard starting, weak throttle response and poorer fuel economy. Both are checked at a regular service and replaced when worn.

  • Disc brake fluid

    Brake fluid absorbs moisture over time, which lowers its boiling point. Have its level and condition checked and change it on the interval in the owner's manual.

  • Tyre inspection

    This bike runs 100/90 - 18 / 150/70 - R17 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.

  • Battery & electricals

    The battery is listed as Maintenance Free. Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.

Triumph Bonneville T120 specs explained

What the technical terms on this page mean.

ABS
Anti-lock braking system. It stops a wheel locking up during hard braking so the rider can keep steering. A single-channel system works on one wheel, usually the front; a dual-channel system works on both.
Liquid cooling
Coolant circulates through the engine and a radiator, keeping temperatures steadier than air alone, especially in traffic or under load.
Kerb weight
The weight of the bike ready to ride, with its fluids and fuel, but without a rider or luggage.
Bore x stroke
The cylinder's width and the piston's travel. A larger bore relative to stroke tends to favour revs; a longer stroke tends to favour low-speed pull.
Compression ratio
How much the fuel-air mixture is squeezed before it is ignited. It is one of the factors behind an engine's efficiency and power.
