ball bearings

[maxi81]

Does anyone know what size ball bearings are used for the steering head for a RM 400T? I took my old balls to a bearing shop and they sized them up and gave me new ones, but I think they are a bit smaller. I was told you need 18 ball bearings for my bike, but I needed 20. Does that mean the ball bearings I just bought are too small?

Thanks

Not sure what size they are but they do take 18 balls.
Not sure why they leave a gap for 2 extra balls,but suzuki do.
I've been there and just fit the 18 as they specify.

In the B/C/N models they used to fill the entire circle.
BUT they realised this tended to jam and I am fairly certain T had the gap - deliberately.

The air gap is for the expansion of the balls due to the heat created from the super quick handling of the Suzuki's

Seriously, the balls are a std 8mm for top and bottom for the N and T's. I've find usually on near any model there is not quite enough room to fit ball number 19 when the correct size is used

Loose balls you can get from VXB bearings on ebay. Im just not sure if they have metrics though.
