Tires 12-20
Cylander 160-180 and it probably won't run under 140, my experence with 125's is with a Honda CR 125 so the numbers might be a little diferent
FYI do not over tighten that can lose you compression
yz 125 use the same plastics from 1996 to 2001
I have a 2001 Yz 125 stock Gearing, Fmf Pipes. 60-65Mph
I get 220 psi on my 1994 so yours should be about the same and it won't run with less than 150 psi
Yes it will all yz125"s are the same from 96-2001 hope this helps :)
Yes, you're good to go with it, they are the same part.
no i have a 2000 yz 125 and can beat a kx 125 blind folded
NGK BR9EG is the correct plug for a 2001 Yamaha YZ 125
100/90 x19
no it will not
The bike never had a title. Just have a bill of sales that should be sufficient.
The "vin" number will be on the right side of the steering head tube.
Not much. Except the graphix and the plastics. im not quite sure about the small changes, but over all. the yz 125 is a steal frame up until 2006, then they started making a aluminum framed bike. im almost positive that's your right answer
