Sprocket

Can anyone tell me if it's worth putting a 47t rear sprocket on a hummer 250cc and will this increase overall performance of the bike ie more top end speed and a longer first gear.

Sorry don't know about that its not really a mini...

Parts a readily available for those bikes if you know where to look and the reason i got one is just to get out there and have some fun with my kids they have the atomik i'm actually saving for a honda crf 250 2007 model at the moment the hummer is a muck around for the time being but all in all extremely surprised with it so far i thrash it around a bit and havent had a problem goes pretty good bit heavy but o.k.

Wrong site mate, this is "miniriders" for a reason, those nugget hunks aren't classified as a mini.

its simple a smaller rear sprocket will increase top speeds its only common sense, like everyone else has posted not many people will give you information on that 250 as the site is dedicated to pit bikes.

but its also simple to relize that you have to replace two rear sprokets for every 1 front sproket but also that every 7 teeth on the rear sprocket is the same as 1 on the front so do the math but every1 is right about less teeth will give you more speed but less torque so its up to u

and some ppl also have to get over the fact that hummers arent mini they still work on the same princibles as a mini so stop wasting ppls time and learn what ya talking about

Ive put a 47 tooth on both my daughters 200 and my 250 it is better, but most importantly it makes it a much better bike to ride not having to change gears every 60 feet!
