Great Britain; police-reported casualties in final 2025 data. Includes motorcycle users; severity-adjusted nonfatal injuries. Pooled risk patterns cover 2021–2025.
Deaths rose while total casualties fell
Motorcyclist fatalities increased from 340 in 2024 to 386 in 2025, an additional 46 deaths and a 14% rise after rounding. Serious injuries also increased, from 5,370 to 5,710.
Total casualties fell from 15,960 to 15,447. The serious-injury comparisons use the revised 2024 counts in the latest DfT release, keeping both years on the same basis.
Motorcycle fatality risk per mile
The motorcyclist fatality rate was 128 per billion vehicle miles in 2025. DfT describes it as around 50 times the car-occupant rate.
This comparison measures fatalities relative to distance travelled across each road-user group. Route, conditions and individual exposure affect the risks faced on a particular journey.
Rural roads and the five-year casualty pattern
Across 2021–2025, rural roads accounted for 70% of motorcyclist fatalities and 38% of motorcycle traffic. Male motorcyclists accounted for about 92% of those killed or seriously injured over the same period.
Among reported motorcycle casualties in two-vehicle collisions with one HGV, 9.8% were fatal. This describes the severity of casualties in that collision group.
Helmet ratings and fit
The SHARP programme rates motorcycle helmet safety performance on a one-to-five-star scale. Its guidance emphasises choosing a helmet that fits correctly, fastening it properly and considering its safety rating.
What the motorcycle figures cover
The totals count people injured in police-reported road collisions in Great Britain. A collision can involve several casualties, and KSI combines those killed and seriously injured. Northern Ireland and damage-only incidents fall outside these totals.
Serious and slight injury figures use DfT severity adjustments to improve comparisons across police reporting systems. Historical adjusted counts can be revised, and the series does not estimate all unreported injuries.
