What should i get to maximize the performance on my dirt bike?

Question

I just got an aftermarket exhaust for my ttr 125 4 stroke dirtbike and im wonderin wut else i can get to get some extra performance out of it

Answer 1

Go to BBRMOTORSPORTS.COM and get a Powroll Thrust Chamber and you will get the performance of a aftermarket exhaust without spending 300 bones. Then get a rev box. It will let your motor rev past the stock limit witch will give you more hp. That is a good hp gain for under a 100 bones.



If you want to spend a little more money you can have the flywheel lightened at BBR for a hundred bucks. This will let you motor rev like a 2-stroke and make it pick up RPM's fast. If you do alot of wide open riding, this is the thing to do. "This will take away some of your bottom end."



If you still want more than get a big bore kit. If you do go with the big bore kit thin you will need to go with 26mm carb. The stock carb was not made to handle a bigger bore than stock.

P.S.- It is better to buy a complete kit than have the stock cyl. bore. Watch e-bay for these items and do not buy a china knock-off.

I race motocross in Pa on a yz85. I say the best thing u could get for a ttr 125 is a exhaust. but you could send the bike to pro action or procircuit to get the cyclinder head bored out to a 150cc. Which would overall make it faster and more powerful

Answer 3

I prefer two stroke myself with a powerband.

4 stroke it alright, but if you want power I would put high performance carb on it and bore it out and put a compression release valve on the head.

You can also change sprocket to give you a faster take off, but you lose some on your top end.
