Has any put renthal bars on their f4? I was just wondering if I'd need longer brake lines or cables?

 

I have put some raised bars on mine, not Renthal tho, I just managed to get away with the clutch and throttle cables but did need new brake lines, I went for the two lines direct to the calipers not the OEM setup.

 

Thanks for that, could you tell me how wide those bars are?

 

No worries, they are 75cm from this link.

Happy to help if you need any more info etc. Any higher / wider you are running into problems with the wiring from the clusters (as it was I had to extend the horn wiring) and you would certainly need a new clutch cable.
