Have you got a solution for the speedo?
Depends on the wheel, luckily for mine it was simples, just had to file down the plastic pins from the sensor to fit flush with the Thundercat wheel!
As for the calipers not sure if you've got an R1 or R6 front end or what year, early ones are the same I believe.
I hope it's the entire front end (wheel, fender etc)
If not the fazer wheel and calipers will need spacing out!
Don't be surprised if the steering lock stops don't hit, and chances are the controls will hit the fairing before they did anyway- this isn't an issue, just reduces the turning circle, not only that but if using the clip on bars there may be the opposite issue of clearance against the tank.
You can keep the fazer handlebars but will obviously need to drill out the top yoke before fitting!
If you got it for the right price it's a good upgrade, have a day ready to go through it all
