Lets use a yamaha R1 as an example:
Assuming you found out the tyres were the same size front and rear, how do you guys find out if the wheels fit the bike you want to use?
Is the info published anywhere in order to make comparisons?
Surely there are other manufacturers bikes with the same size wheels?
This project lark is much harder than I first thought, which you guys know already! |
I intend building a lightweight aircooled special in the not to distant future (although not intending to use wire spoked wheels), having previously built several Harris Magnums as well as owning Moto Martins and Bimotas and have been modifying and upgrading bikes since the early Eighties and it has always involved a lot of research.
Personally I would prefer a 5" wheel with a 170 tyre but once you have decided on Rim sizes it is a matter of checking to see whats suitable.
Firstly you beed to know what sizes you already have, that includes Spindle sizes and therefore bearing inner diameters, Disc Spacing, Hub width, Gap between forks, Speedo Drive fitment, swingarm gap, chain alignment.
Ducati for years fitted 320mm discs with 10mm offset and 64mm mounting Boss with fixing bolts on a 80mm PCD.
Luckily they were not alone in using these sizes. The lkes of Aprilia, Moto Guzzi, Yamaha and a few others also used these sizes. Sometimes the Disc OD changed, 276mm, 280mm, 290mm, 300mm disc were/are all available.
Yamaha were using a 64mm Boss with 80MM PCD back in the late 70's
Back then front spindle sizes were often 15mm and have increased over the years.
The Honda 400/4 I had in 1980 had Yamaha XS250 Fork Lowers, wheel, discs, calipers, spindle and speedo drive fitted allowing me to run twin discs and get away from Hondas horrible pivoting caliper that often seized up, A couple of years later my 2nd 400/4 was fitted with wheels and Forks from a Yam YPVS 350.
