| I wouldn't fit them based on what I've seen from various accidents. A mate of mine had some on his SP1 and they bent back and put a hole in the radiator which put an end to the track day. And the radiators are £500! This would not have happened if they weren't fitted and the bike would have just slid down the road.
I've seen them bend and do more damage, in most cases, than would have been done had they not been fitted (IMHO). |
