With a 12t front

[SCOOTER450R]

I put the 12t on last night and I rode it around alittle.
You really have to shift fast but it really wasn't bad but I only rode it maybe 5 minutes.
It felt like my uncle's 250r.
Maybe I'll have time to ride more over the weekend:D
Also the chain looked fine going around the sprocket it wasn't too tight and the chain adjusted fine

I really like the 12t. I have 3 acres so everything is short so it didn't seem bad to me at all. My wife and I went around our mile section and it was running fine for that because we never really run wide open. She rides a 300EX so I don't have run hard anyways. We did get on a blacktop road for a couple miles and I ran it hard. I hit the rev limiter easy in 5th.
Anyways all went well and it only cost 17 bucks

I changed to a 13 pretty much right away. I put the 14 back on yesterday and it's staying. I think it accelerates faster with the 14 tooth. My buddy still has the 13 and I can beat him pretty bad. He weighs about 50 pounds more than me though. He is switching back to a 14 also.
