2007 Triumph Rocket III Overview

Triumph Rocket III is a custom / cruiser motorcycle, displacing 2294 cc. Power comes from a Four stroke, longitudinal three cylinder, DOHC, 4 valves per cylinder engine, a compression ratio of 8.7:1. On the performance side, it delivers 103.6 kW @ 5750 rpm of peak power and 200 Nm @ 2500 rpm of torque. Top speed is factory-quoted at 219.4 km/h. On the road, the 2007 Rocket III tips the scales at 350 kg, carries a 24-litre fuel tank, offers a seat height of 740 mm and spans a 1695 mm wheelbase. That's roughly 49.4 kg heavier than the average custom / cruiser motorcycle in our database. The full 2007 Triumph Rocket III spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2007 Rocket III - Pros & Cons

Strengths

Strong power output: With 103.6 kW @ 5750 rpm and 200 Nm @ 2500 rpm of torque on tap, the Rocket III is no slouch for its class.
Accessible seat height: A 740 mm seat height keeps this manageable for most riders, which helps confidence at parking-lot speeds.
Large fuel range: A 24-litre tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.
Low-maintenance final drive: Running Shaft final drive cuts out the regular chain cleaning and tensioning that most bikes need.

Considerations

Age-related wear: Nothing specific stands out as a weak point on the Rocket III - the usual used-bike checks (service history, consumables, tyres) apply.

Wear Points & Servicing Notes

Cooling system servicing

Rocket III's Liquid cooled setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.

Brake disc and pad wear

Braking up front comes from 2 x 320mm Discs, 4 piston calipers - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Suspension condition on used examples

The Rocket III's suspension runs 43 mm Upside down forks at the front. The rear uses Chromed spring twin shocks with adjustable preload. Fork-seal condition and rear linkage play are the two things worth checking before buying used.

Final drive maintenance

The Rocket III uses shaft final drive: essentially maintenance-free day to day, with periodic gear-oil changes the only real service item.

Frame & chassis check

Built around a Tubular steel, twin spine, the Rocket III's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.

Handling the weight at a standstill

350 kg puts the Rocket III toward the heavier end of its class. It's most noticeable at walking pace; once underway the mass settles into the handling rather than fighting it.

Rocket III - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2007 Triumph Rocket III, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy Rocket III should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a Rocket III's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
