    Anyone have any gearing suggestions for NJMP's Thunderbolt track on a 600?

    -1 on the countershaft is a good start. I also run +2 on the rear, 06 ZX6rr.

    That's what I was thinking based on what I've heard. You get deep into 6th with that combo? I might bring some bigger rear sprockets as well.

    -1 front

    +2 rear should be right for a decent pace. I had a +3 but you have to hit 6th before the bridge and you will be on the limiter down the straight.

    -1 +2 on a 2007 ZX6R has me right in the power band as I go under the bridge, I am just bouncing off the limiter as I hit my brake marker. I tried -1 +1 but I lost some drive coming out of 2,5 and 7 and dropping a gear there wasn't an option.

    Can I get some numbers? I have no idea what the stock was.

    5 gear setup

    Hey Rick, you may want to let this person know that gearing is setup for use of 5 gears and not all 6. This makes a big difference. Unless ur running 1:29 or below, I'd suggest u start with 15/44 or 43 and again ur only using gears 1-5. Or u could run 15/47 (6 gears setup) and short shift like crazy. A buddy of mine runs that and likes it. He runs 1:31 laptimes, so it could work for u. It's all rider preference. Hope this helps.

    My 04 GSXR 600 is -1/+2 (15/47) and it works to get me around Thunderbolt in the :33's. I'm clicking 6th at the start/finish and holding it for a bit until marker 4. I thought about going up another tooth in the rear but I'm worried about running out of gear in the decreasing radius, I'd rather not be shifting through there.

    What gear do you downshift to for turn 1?
