A 2000 GSXR600 with the cowl on. It was like a mountain bike. I got nothing resembling forward thrust from the throttle. I had no Idea the difference was so great. No wonder people recomend these things for beginners. Now I understand why all the guys I ride with talk so much about how to get the front end up, and all I want to know is how to keep it down. I had to draft a buddy who was riding a ZX-9 to make any kind of a move, and sitting up just killed any progress. I pulled out and rode up next to the ZX-9, and when I topped out at about 160 indicated, I made motions with my feet like I was pedaling a bicycle. He nodded up and down. You can whack the throttle any time, in any gear, without getting hurt. I revved the whee out of it, and it didn't seem to help. The brakes sucked too. Maybe I shouldn't have ridden it back to back with my Bus.
