XBR Wheel Choices

[Moto63]

Hi silver, I think you,ll find the disc from the Honda cb750 (80,s model) bolts straight on to the rs hub and needs only a bit of work to space out the xbr caliper for it all to line up correctly . Regards Michael

Hi Dave,
the diameter of the disc fitted to the RS wheel is 280 mm but I did not source this so I have no idea what is standard size. The disc on the XBR front wheel is also 280 mm.

Chris you must have the CB750 disc. The CB250 is only about 240mm.
I'll get a CB750 disc.
Thanks.

So I had a look at the spoked wheels on Alison's XBR.
I was told that both front and rear are 250RS hubs.
Both wheels are 36 spoke, in groups of four,
Front rim is marked:
J 18 x 1.85 4 80 DOT, also DID JAPAN 1.85 x 18 96 --14 07 --
Tyre: 100/90-18 Avon Roadrider
Rear rim is marked:
MORAD SPAIN 2.50 x 18 36TC 23/5/08 E DOT
Tyre: 120/90-18 Avon Road rider
Hope this is of some help
