If ya got stock whack that on, if not it should be fine dude they inner to loud! i did mine on a CG125 and managed to get like 10kmh overo n the speed avoidance or w/e it was! and speeding on the mod 2, i was litterly flat out everywhere!
Well mine was 7 years old, the instructor said the oil had never been changed!
Wouldn't go into 3rd without about 5 attempts, just drove around the 40 zones in 2nd because I gave up rofl
And just couldn't get use to it in general, had to push down loads on the rear brake to get a decent slow ride speed going
Having said that I passed with no minors so it couldn't have been that bad, but would have been so much relaxed on the DT + I don't want to risk anything like that happening again on the mod 2
lol toy the examiner went round with almost a magnifying glass at mine he would of told me to **** off if he had seen my DT how it is now
Gonna try and find a stock xpanny somewhere better to be safe than sorry really
