This kit uses class C3 bearings suitable for heavy-duty use even at high rpm, therefore also suitable if a super-reduced kit is installed.
We chose to use KOYO bearings as they are the ones used originally by Suzuki and the only ones who along with seals and gaskets to ensure a review of the original Suzuki gearbox in a workmanlike manner.
The kit includes everything you need to overhaul the gearbox, the rest of the components such as roll cages, post, etc. must only be replaced if worn, in which case, please send us an email and we will provide all the necessary component.
