Uprated by 15%, this spring is classed as an over 90 kilos rider.
To fit the Showa rear shock only!
It is no good just winding up the standard spring, a bike is set at the rear by the weight of spring.
For fitment to all earlier models of 4rt with the Showa shock and also the new 260Repsol and 300RR models.
Will also fit the 315.
