Hehe, I know what you mean about the drag bikes. My friend has a 900RR engine, with a little modification

putting out 160rwhp N/A on his dynojet. He fired it up and was playing around with it yesterday. It has a solid rear suspension right now, and a lengthened swing arm. He was warming it up on the dyno with a road race tire and when he finally started playing around with it, he spun the bike's tire on the dyno drum when he did his 4th gear roll on.
Keep in mind, this engine has been wedged into a CBR 600 F2 chassis, with 600 plastic on it.

Can you say... sleeper? Hahaha.
