If you own or are considering buying a 2004 Yamaha Xt 660 R, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to motorcycle suspension: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks. With relatively low average mileage of 16,442 miles, many of these vehicles are still in good mechanical condition.
Motorcycle suspension — 0.5% of failures
Motorcycle suspension issues account for 0.5% of MOT failures on 2004 Yamaha Xt 660 R models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Motorcycle wheels — 0.3% of failures
Motorcycle wheels issues account for 0.3% of MOT failures on 2004 Yamaha Xt 660 R models. Wheel failures include cracked or severely corroded alloy wheels, missing or loose wheel nuts, and wheels that are insecurely attached. These are safety-critical and relatively rare compared to tyre failures. Typical repair costs: £100–400 per wheel. Pre-MOT check: Visually inspect wheels for cracks, especially around the spokes and rim. Check that all wheel nuts are present and tightened. Look for signs of impact damage on alloy wheels.
Motorcycle brakes — 0.3% of failures
Motorcycle brakes issues account for 0.3% of MOT failures on 2004 Yamaha Xt 660 R models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
