2 stroke
2003 yz85 is a 2stroke motor cross bike with a 85cc motor or 85 cubic capacity engine you have to mix oil and fuel together
YZ85's are actually an exceptional bike.. but you have to stay on top of the maintenance.
depends what stroke (4 or 2) uh the compression (low or high), allot of crap, my brothers 07 yz85 went 80 but that's with some work. i would guess that stock it was 70 maybe 65
A yz 85 Stroke is 2
Depends how big you are. Yamaha makes really good bikes. maybe like a ttr125 or ttr225 or yz85 or something.
The yz would always win because its a 2 stroke race bike. Even the yz85 would beat the crf150r or the crf150f.
definatly a yz 85 cause they have way more power that any other bike like a kx85,rm85,and cr85 i have a yz85 very fast a has a very smooth ride and really loud with a 2 stroke pipe
Yes. It's a good 2 stroke and reliable. I'm 13 and I've got a big wheel Yamaha yz85. I think you might need a small wheel unless your big. If it's your first bike you'll be okay because it's not overly powerful.
The stock compression ratio for a 2003 Yamaha YZ85 is approximately 8.6:1.
A stock Yz85 is capeble 0f 64 mph. With proper upgrades, 70 mph can be achieved.
For trails XR100-XR650.For motocross YZ85-Yz125no that is not. the best is a razor electric dirtbike
