hi all lookin at buyin bt45's for my z1a do i go for 100/90-19 and 120/90-18 v rated tubeless if so can you still fit a tube in on a standard steel rim cos i dont think they do a tube type.
thanks

i have - no problem

cheers thats what i will do then

I would go for stock imperial sizes.
They're still tubeless but in particular the rear will wear better.

If you want an innertube there's one here.

So this is probably a stupid question but here goes anyway, if you don't put an innertube on a spoke wheel, wont the air escape out through the spokes?

Not if its a bmw. Think guzzi are the same. The spokes are fitted in the side rather than the middle in a seperate bit on the rim etc so not actually inside the tyre.

Thats a very good choice of Tire. I run BT 45's on mine and there brilliant ,very planted ! & definitely stick to STD sizes Tires on Std rims or you will regret it ...handling will be lesser ! Try not to get caught up in this whole big tire thing , as there's a lot more to it than meets the eye . It will rob your H.P. if you have 125 hp plus, well yes .....you need a bigger footprint on the tarmac then & you can afford to sacrifice some Ponies for the privilege. This is why you won't see 120 front & 200 section rear tire's on a Manx Norton or G-50.

thanks for that so the std sizes state they are h rated not v is this ok.

up to you - i run (and always have) metric tyres that are V rated and don't have a problem. Having said that i don't do 130+ on my Z.
