About the Triumph Rocket 3

Overview

The Triumph Rocket 3 is a cruiser motorcycle from Triumph. It was launched in 2019 and is still on sale. Cruisers are built for relaxed riding, typically with a low seat, a laid-back posture and an engine that pulls from low revs. With a 2,458 cc engine it sits in the big-bike, 800 cc-plus class.

Engine and performance

Power comes from a 2,458 cc three-cylinder liquid-cooled fuel-injected engine that makes 182 PS at 7,000 rpm and 225 Nm of torque at 4,000 rpm. Peak torque arrives low in the rev range, at 4,000 rpm, which makes it relaxed to ride in traffic. Its bore is wider than its stroke (110.2 mm x 85.9 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 569 PS per tonne; by that measure, its performance is at superbike level and rewards an experienced rider. The claimed top speed is 220 km/h. It has electric start.

Gearbox

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

Chassis, brakes and tyres

It is built around a full aluminium frame. At the front, the suspension is showa 47 mm USD 1 1 cartridge front forks, compression and rebound damping adjustment, 120 mm wheel travel. At the rear, it is fully adjustable showa piggyback reservoir RSU with remote hydraulic preload adjuster, 107 mm wheel travel rear suspension. Braking is by twin 320 mm discs at the front and a 300 mm disc at the rear, with dual-channel ABS. ABS on both wheels keeps either tyre from locking under hard braking. It rides on 17-inch front and 16-inch rear alloy wheels with tubeless tyres — 150/80-R17 at the front and 240/50-R16 at the rear.

Size, comfort and range

The seat is 750 mm off the ground, which is low and makes it easy to put your feet down. It weighs 320 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 2,500 mm long, with 1,677 mm between the axles. Its 18 L fuel tank and claimed mileage of 14.6-20 kmpl work out to roughly 360 km per tankful on paper; real-world range is usually lower.

Features and equipment

Equipment includes a digital instrument console, an LED headlamp, turn-by-turn navigation, cruise control and service due indicator. Safety equipment includes engine kill switch, traction control, low fuel indicator and low oil indicator. It has four riding modes: Rain, Road, Configurable Rider and Sports.

Owning one

The manufacturer's warranty is 2 years/Unlimited kms. For the Triumph Rocket 3, Mechiee offers a fixed ₹17,999 doorstep service.

Who it suits

It is best suited to relaxed riding and unhurried weekend trips. Its low seat also makes it approachable for shorter and newer riders. 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 42 psi front and 42 psi rear, solo or with a pillion. Its shaft drive is nearly maintenance-free; the final-drive oil is changed at long intervals.

Maintaining the Triumph Rocket 3

  • 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 Double Disc, 320 mm and Disc, 300 mm 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 150/80-R17 / 240/50-R16 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 Rocket 3 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.
OHC / SOHC / DOHC
How the engine's valves are operated. OHC and SOHC mean one overhead camshaft; DOHC means two, which usually allows higher revs and more power from the same size.
Fuel injection
Petrol is delivered by an electronically controlled injector instead of a carburettor, which helps with easy starting and steady fuel economy.
Liquid cooling
Coolant circulates through the engine and a radiator, keeping temperatures steadier than air alone, especially in traffic or under load.
Cruise control
Holds a set speed without you holding the throttle open, which reduces fatigue on longer, steady stretches.
Upside-down fork
A front fork mounted the opposite way round to a conventional one, with the thicker tubes at the top. It is typically stiffer under braking and cornering.
Tubeless tyres
Tyres with no inner tube. A small puncture usually loses air slowly, which makes roadside repair easier.
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.
