Does anyone know what the part numbers are for the front & rear wheel bearings for the MC21SP. Not quite sure which ones they are in the parts manual.

Thanks,
Jez

looks like from the parts section

91075-KV3-721 x 2 fronts

91074-KV3-721 x1
91073-KV3-700 x1
91072-KV3-700 x1rears 3 set's

thats from a SP NSR250R8N

I would get a second opinion as the numbers in the parts section dont match the diagram?

My r Model needs (as im after a set to)
2 x 91054-MN8-741 front
2 x 91072-KV3-700 Rear
1 x 91073-KV3-700 Rear (again 3 bearings for rear)

Cheers rc46, thanks for clearing that up.

Hi,

The front wheel bearings are a standard size for my R model, should think they`re the same size for the SP wheels.

Maybe someone can confirm this on here?

I haven`t looked at the rear ones yet so I don`t know the sizes.

I bought the bearings for the front wheel from a bearing supplier in England, BSL Brammer.

They`re SKF bearings, numbers are 6004 2RS, it`s a standard bearing size, the 2RS bit means two rubber seals.

Should be cheaper to get them from a bearing & seal supplier than the original Honda parts.

Roy.

had mine done at the weekend, fronts are standard Honda fit everything bearings, but i was told the rear was different.

Anyone got the SKF numbers for the rear bearings for MC21 R?

Just happen to have a set of Honda rear wheel bearings (not in packets) on the desk!

2 x 60/22-RS
1 x 62/22-2RS

Both types have 2 rubber seals, despite the smaller bearings not having "2RS" in the code.

As Roy says, they can be bought from any bearing shop, and substantially cheaper than from Honda.
