I have a 91' lt250r. My front sprocket has 13 teeth. I think the stock sprocket has 12 teeth. What kind of low/top end differances would this make?

thanks,

Going from a 12 to a 13 will give you a higher top speed and make it feel like you have less low end power for any given gear.

 

A 12 is what i would recomend. I've tried an 11, and you've got tons of low end and that's it.A 13 tons of top end and thats it. A 12 is the best ot both worlds. i'd go with a 12.

 

You may want to play with the rear sprocket as the change wont be so dramatic. A lower number out back will yield more top end while a larger number will give you more bottom end (just the opposite from the front).

 

I have tried 11, 12 and 13 and raced all three my best results are with 13. First gear is so low on my 92 LT250r that 13 gives it just a little more pull.

 

I agree with most of the posts, but I would avoid a rear sprocket change because when I increases mine to 44 it was very close to my skidplate and the first hard hit (rock) caused the skidplate to rub against my rear sprocket and chain. Stick to an 11 for dunes and a 12 for everywhere else.

 

You are correct Vegas, however, I would imagine it depends on the brand of aftermarket skid plate you have. Going with a smaller front sprocket instead of a larger rear, not only is a more drastic change but also wears out the chain and front sprocket faster. Keeping the front sprocket as large as possible will put less strain on both of these components. This is mearly a fact I wished to pass along but may not be significant enough to base your decision on.
