Try a Pro Circuit or BBR, I use the Pro Circuit T-4 and I got a ALMOST 2 HP GAIN IN PERFORMANCE. But it is up to you for pipe selection. You got Pro Circuit, BBR, FMF, Big Gun, Yoshimura etc. there are a bunch of pipes. They all can be pretty loud too, so you may want to check if it is okay to ride in the neighborhood before putting on a pipe, but if your on alot of land you should be ok. I have a KLX/DRZ125L (simular to TTR-125) and it has a procircuit t-4 and it works good, you should try it.
ttr 125
a lot about 20mph
the ktm 105 is way faster that a ttr
no
Yes a pipe would make it go faster and it would be alot queiter than what it is now . It will also help prevent backfire of the engine .
the Yamaha ttr125 goes about 50 to 55 mph
I think one has disc brakes & the other has drum brakes but not sure which is which.
either get a yz85 or a yz125 the ttr125 is to small for u i have one i am 5ft 5in and it is way to small for me
TO MAKE THIS FASTER YOU NEED TO BUY A NEW AIR FILTER AND EXHAUST PIPE. WWW.MONSTERSCOOTERPARTS.COM install a first class Johnson rod kit.
