i had the full 57mm system fitted to my 999s last year it was a bit of a bugger to get lined up the old style end boxes used to split (i went though 7 in the end)see att pic the new ones are stronger ,but ive yet to see one!!! its on back order........... and the problem with the old cpu is thst if you dont tell the dealer heŽll stick in the red key and lock the cpu to the bike(800) but the good news ... loads of power compared to standard looks great not too loud 89.6db before i was black flaged |
