hello guys,

Iv googled it but cant find an answer....

I have a zx9r c engine and want to know the coolant hose size as I need to order some silicone hoses for my engine....

Thanks
Jim

pretty sure there 25mm as per most bike engines

Agreed 25mm and 10mm

Thanks guys,

Iv seen that there is the standard reinforced silicone hose on ebay and also this vacuum silicone that also says for coolant....

would this be ok for the main hoses as it is more flexi?

Jim

Three ply silicone the minimum for cooling, don't hold much hope for the single ply lasting long on a cooling system running at 90 degree, at close to 1 bar pressure

thanks

the only reason i asked is cause it states coolant in the list of uses....
