Tall first gear

[michael68]

I have a 2001 KX 250, first gear is very high for trail riding is there anyway I can fix that?

You can lower your gearing, and overall speed in each gear, by changing either front or rear sprocket.
This will make your bike feel snappier and have an easier time wheelying.
Larger in the rear or smaller in the front.

If the chain and sprockets on the bike have some hours on them, it is not advisable to just change sprockets. It can cause premature wear due to the change in shape.
Changing chains and sprockets together is best practice.-BIG DAN

I guess we could sing you a verse or two of "welcome to trail ridden race bikes". Guys that just got off trail bikes and onto mx rigs learn it pretty fast. It is too bad that 'green' didn't keep building things that used similar tranmssion cavities that had wide ratio gear sets.

i like narrow ratio for trails

I think adding one tooth in front is like adding three in the rear

Actually it's the opposite sparky.....except 1 less countershaft tooth is around 4 tooth difference on a 13/50 stock gearing setup.

13/54 is 4.15 and 12/50 is 4.16

We need to just look at MotoCross Action to solve any gearing delimas: For years they knew something that the factories have never figured out. That is that ALL motocross bikes came from the factory needing a change to a rear sprocket that is one tooth larger than what was sent by the factories.

Well sure, if you are going to ride on narrow trails.
