| What's the rear spring now?
My 04 999 came as standard I think with a 6.5Kg rear spring which way too soft, JHP replaced this with a 7.5Kg spring and the bike handles a million times better now.
I believe the 05 bikes now come with a 7Kg rear spring (not sure whether this is mono or bip though)
I weight just under 14 stone, so use that as a benchmark |
