chain sprocket

hey just curious because i heard of some people doing this, but has anyone had any experience putting on a 15 tooth sprocket? as far as i know our 250's come stock with a 14 and just wondering how much it would effect our bikes if changed to a 15. it just seems like 1st gear is so short.

I changed the rear sprocket to a 47 tooth shortening the gears and giving more acceleration. I didn't want to lengthen the gears and slow the bike down more than it already is.

I have the 15th on mine and I like it a lot. Brings the rpms down about 500, enough to reduce the annoying vibrations on the hwy. Works great for tight canyon riding too.

We put a 15 / 43 on my sons and made a big difference. Can actually ride down the highway without screaming the engine.

I have a 15T on mine and it keeps the rpm'd down while on the freeway but at the same time your take off from a stop does not suffer much.
