Moderate sample. 422 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2003 Honda CB600 passes its MOT at 87.1%, comfortably above the UK average of 80%, which is a strong sign of long-term durability for a machine now over 20 years old. However, one in five of these bikes (22%) have recorded a dangerous defect at some point, so thorough pre-purchase inspection and maintenance history checks are essential.

These CB600s show remarkably low mileage for their age, with a median of just 15,892 miles, suggesting many have been cherished or stored rather than ridden hard—a positive indicator for mechanical integrity. The average bike still picks up 1.75 failures and 6.2 advisories per test, so budget for routine wear items and don't skip the pre-buy inspection, particularly on brakes and emissions systems where the advisory count suggests most wear occurs.

The 2003 Honda Cb600 passes its MOT first time at roughly the UK average rate (87.1%) — solid but worth checking this vehicle's history carefully.

⚠️ Over 1 in 5 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.

For context
Good baseline reliability. A 87.1% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 6.2 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 422 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.

What tends to go wrong

Across 422 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Tyre wear 71.1%
Front Tyre worn close to the legal limit · Rear Tyre worn close to the legal limit · Rear Tyre tread depth is below minimum requirements of 1.0mm · …
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Lighting 44.2%
Drive chain slightly loose · Rear reflector on motorcycle missing · Headlamp aim too low
Usually cheap to fix. Worth confirming all lights work before collecting.
Brake wear 37.8%
Rear Brake pad(s) close to minimum limit · Front Brake pad(s) close to minimum limit · Rear Brake disc(s) slightly worn · …
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Exhaust & emissions 37.1%
Exhaust noisy
Other issues 15.6%
Drive chain worn but not considered excessive
Suspension & steering 10.5%
Steering movement slightly 'notchy'
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.

high mileage

Half of all 2003 Honda Cb600 vehicles fall between 10,067 and 24,281 miles.

Is the mileage you're seeing normal?
Under 10,067 miles — lower than most. Could be great, or could be a vehicle that rarely moved. Check test frequency and mileage progression in the MOT history.

121 vehicles still getting MOTs in 2025 — 55% of the peak remain.

220 121 2014 2025

Based on vehicles from this manufacture year that had at least one MOT test in each calendar year. Data from 2014–2025.
* The 2020 dip reflects the government's COVID-19 MOT exemption, which allowed certificates to be extended by six months — fewer tests were conducted that year.
