The ol' 660 is a fantastic bike but I reckon it could be made a whole lot better by shedding a bit of weight. After all, it weighs about the same as an R1 but it's 2/3 the engine capacity.

So, how about some ideas on how to make it lighter? Here are some of mine to kick things off:

• After market cans (up to 6kg lighter)
• Wavy brake discs (??? lighter)

A couple more but depends on riding conditions

• Remove radiator fan (mine's never ever been on)
• Remove side-stand

What else?
