KOYO crankshaft bearing for motocross, enduro FANTIC XE, XX / HONDA CR R, CR / YAMAHA YZ 2T 85,125cc...

The choice of bearing is essential for a highly prepared engine, at high speed the bearings vibrate even if you don't necessarily feel it!

These various vibrations create a force and therefore slow down the crankshaft!

In addition, a very powerful engine between torque and high revs is likely to literally explode the bearing! These are the reasons why I offer you this KOYO bearing!

Used for competitions, it is ultra resistant from the ball to the cages.

Dimensions:

-Ø64x55mm

-Width: 16mm

It will bring you:

-Better bearing lubrication thanks to its architecture

-Less vibration thanks to its studied polyamide cage

-Extraordinary resistance thanks to studied play and the most resistant materials in the world

-Even an excellent aesthetic with its KOYO engravings.

They therefore fit on original crankshafts and all competition crankshafts using an original tang size. Made at KOYO.

The price concerns a bearing, sold individually.
