Change adjust replace upgrade....
If it's your first trackday I'd look at it in this respect...
CHANGE suspension settings and tyre pressures...,
Look at setting up the correct sag as usually you'll add a little more preload because you don't have the same dynamics as riding on the road. Tyre pressures.... Contact your tyre manufacturer / dealer and they should provide you with information on pressures to run for your tyre make and model.
If not there is usually someone at a tyre changing facility at the trackday who can advise you on this too.
ADJUST riding style ....
Ride on the balls of your feet and kiss the mirrors...
Foot position and placing body weight correctly make things a lot easier. You don't want to be fighting the bike ...
REPLACE... Underwear if you push the boundaries too far...
learn from the mistake, grab the bull by the horns and tame the beast again.. Don't let it beat you...
UPGRADE... Enjoy the learning experience and if you choose, you can expand and upgrade as you see fit...
You normally get 5 or 6 sessions so use the morning sessions to focus on learning the lines and picking the apex's . Look at body position and keeping your arms relaxed. Just like riding a horse, just give it it's own head , you don't want to fight the bars to get it to do what you want..
Depending on how well the suspension set up is you usually have a couple of riding style options... Heavy braking into the corner nose down late apex and point and shoot on the throttle again but if suspension is too soft, you'll run wide on the exit...
I prefer to brake a little earlier, settle the bike and carry a little more corner speed and slowly roll on the throttle as you continue through and out the exit of the corner.
If your TRX has no special suspension upgrades to suit your weight and riding style , I would air on the second option. Have a little faith in your tyres as most tyres have more than ample grip levels and feedback when pressures are set correctly..
Enjoy the day and try a few options to get the feel of the dynamics of the suspension and bike....
Look at your gearing too, 16/41 will still get you 220+ down the straight and close to redline...
Remember peak torque on the TRX is 6000rpm and peak HP is at 7500 so no real need to run too far into the redline...
