We have had an under seat pipe for this bike since the day it was launched
- but it depends what price you see as affordable - to work properly you need two cans, a new under tray, a new battery box, a new water tank, relay and fuse box mounts, number plate brackets, indicator mounts and of course some pipe work. All this needs to be in stainless steel and preferably powder coated as well
It needs to run perfectly with a TOR tune so everyone can get one, it needs to make more power than stock and hopefully a lot more (unlike say the Black Widow system that actually lost power)
You then need to make all this in to a kit that anyone can fit and does not involve cutting or welding etc so the bike can always go back to stock
We do this and have sold thousands of them over the years at £895. I think this is a very reasonable price but obviously to many it is not....
