The 1999 Honda SLR650 passes its first MOT just 74.6% of the time, which is 5.4 percentage points below the UK average of 80%—a meaningful gap that suggests these bikes need closer pre-purchase inspection. About 1 in 6 (15.6%) will have picked up a dangerous defect at some point, which is a legitimate concern for a buyer.

These bikes are typically running around 17,400 miles at test, which is reasonably low for their age and points to careful use or light mileage ownership. When they do fail, it's usually a couple of issues (1.32 failures on average), but advisories stack up at 4.3 per vehicle, so budget for wear-and-tear repairs—get a full pre-purchase inspection focusing on the braking system and any previous dangerous defect history.

We have limited data for the 1999 Honda Slr650 — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

What tends to go wrong

Across 167 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 46.6%
Rear Tyre worn close to the legal limit · Front Tyre worn close to the legal limit
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Brake wear 20.2%
Front Brake pad(s) close to minimum limit · Front Brake disc(s) slightly worn · Rear Roller brake test indicates slight fluctuation of brake effort · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Other issues 17.1%
Drive chain worn but not considered excessive
Lighting 11.6%
Drive chain slightly loose · Rear Drive chain sprocket slightly worn · Headlamp aim too high · …
Usually cheap to fix. Worth confirming all lights work before collecting.
Suspension & steering 11.3%
Nearside Front shock absorber has light misting of stanchion · Steering movement slightly 'notchy' · Rear shock absorber has a slightly reduced damping effect
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
Exhaust & emissions 7.9%
Exhaust noisy
