The key differences between Honda’s works clutch and all previ- ous clutches is that Honda’s engineers saved weight by lessening the number of springs in the unit. And what springs they did keep, they traded for high-end, high-priced titanium coils. The secret clutch had been bulletproof in the hands of the race team and would be icing on the cake of Honda’s 2009 flagship motocross bike.
