Do you have the proper spring rates and such? May want to run this by Kent @ GMD Computrack because maybe if you're pushing the limits, it could be that the bike's just not hooking up for you... idk, just a thought. Good luck!
You do realize a 600 today makes more horsepower than some small econobox cars do right? At that, you realize said cars weigh a few thousand lbs. you combined with the bike is what...650-700lbs or so? No. You are not too big
I'm 230, and I can consistently podium on my SV650 now. So no, you are not too big to be competitive on a 600 at the club level. As a pro, well... yeah, you are too big.
Honestly, when you reach a certin level, yes, your weight will hood you back. A lot. But if you're asking this question, you're not at that level.
I'm 230-240 before gear and raced a well prepped 600 all last year and part of the season before in novice. I could never do better then 4-5th usually. Jumped on a 1000 and went straight to 1st place in novice. I actually finished better in the 750 classes then the 600 classes on my 600 for some reason?(fewer entries maybe?) So yes, at your size I would say you will be more competitive on a 1000 vs. a 600. I will say that the 600 gave me plenty of practice at pushing harder and chasing guys around the track which I think has helped me on the 1000. Just lackluster finishes with no podiums. Now I just need to transition more to a point and shoot style for the 1000 vs. the high corner speed style of a 600. My .02
Im 215lbs without gear...and i race a 675. Granted, i lose out to the R6's and shit like that on the straights, but i enjoy riding the 675 and i know that there are lots of people who could go much faster on my 675. Therefore neither the bike nor my size are limiting factors. Race what makes you happy.
What would you guys consider too large/big on a pro level? I'm currently 6'2" 220lbs before gear and 238lbs with gear. I'm not saying I'll ever get to a professional level, but if one day by David Blaine's grace I got there would I not be considered competitive because of my size?
Anybody know how big Luca Scassa is? That's another big guy that can apparently rock a 600 pretty good.
