It's madness letting anyone ride your hard earned 'Busa, in saying that, I have let only one good mate ride mine and he is a really experienced GSXR pilot. He also has the resources to fix or replace my bike. (crazy as it sounds, he didn't actually enjoy riding it, he prefers his lighter GSXR1100J but he DID like the engine and the fuel injection response)Only 2 people I would let ride the L2 , both are good mates , and would either buy it outright pre-damaged price or fix it , and or give me one of their bikes and cash . Really makes me feel sick just thinking about all this though , not a life lesson you want to learn from . Luckily one has their own Busa and the other just sold his fairly similar set up Busa and won't probably want to ride mine anyway .
I learned by other peoples bad experiences re loaning bikes and cars.
There is only one person that knows your bike through and through and is trusted to ride it safely... and that is YOU!
