The springs in the primary basket dampen load changes between the crankshaft drive, clutch and gearbox. For engines up to around 30 hp, a standard spring setup is often the right choice because it controls the primary drive sufficiently without working unnecessarily hard. This is particularly interesting for road engines that respond cleanly, remain easy to modulate and do not run permanently under maximum load.
The spring kit is intended for engines in which the primary drive is loaded more heavily than in standard condition, but does not yet require the hard spring configuration for setups over 30 hp. Typical areas of application are powerful street engines, touring setups, sporty everyday engines and cleanly built smallframe engines with a suitable primary cage. The springs do not replace an inspection of the entire primary drive: basket, repkit, pads, clutch, sprocket and bearings must match the performance level.
Only consider primary basket, repkit, rivets, screws or other mounting accessories to be included if they are listed separately in the specific item scope of delivery.
