I've decided to do a 520 conversion on my 06 gsxr 750. For the most part this bike will be a track bike. Any recommendations on gearing on these 2 tracks?

Thanks.

If you are running stock gearing now....a -1 +2 gearing will really wake that
bike up. The mid range on that generation is kinda flat/weak. I have an 07
7 fiddy with just a +2 rear and I love it. I have run t-bolt and lightning several
times with that gearing, no problem. I have ridden an 07 750 with the -1 +2
and it pulls very strong. With just the +2 rear the bike is very smooth and still
has that kick. With the -1 +2 the bike will be slightly more buzzy but its not bothersome at all. You can't go wrong either way.

First let me start out by saying gearing is subjective and changes with your speed and where you are making the speed.

Even with this in mind it all depends, specifically at Thunderbolt, many pros and club racers run these two tracks as five speeds. I'm one of them. We don't race on Lightning anymore so I can't remember specifically what I used. When I go there for a track day I just use what is on the bike, if I'm not going to race a track, I'm not that worried about fractions of a second.

For Thunderbolt I run stock gearing and I'm probably going to need to change it this year to 0/-1, I was really close to the rev limiter last year half way down the straight. I'm going to experiment to fix that this year.

I agree with zman, gearing is unimportant unless you are looking for fractions of a second.

Run what is on the bike, or stock, or whatever. Hell, I ran -1/+2 on occasion at T-Bolt. Lightning sucks and I won't ride there.

When you start racing, and are chasing amateur podiums, then worry about gearing.
