Product Description
Crank seals for all the KR1/KR1-S cranks.
Damaged crank seals is a common problem for two stroke cranks - especially bikes that have been stood up for a long time without being run.
We suspect this is due to the oil being squeezed out from between the seal and the crank over time and the lip of the seal being torn off as soon as it fires.
That said the KR1 / KR1-S is well known for having wear issues on the crank pin - you should certainly check this when dismantling your crank to check whether or not you need our crank pin and seal kit or just seals, see our separate listing.
