I think you'll like the difference. I run a 50 tooth on my mountain bike.... never tested it on any big hills, but I pull a trailer for groceries/laundry etc. real good take off.
will your bike pull you up your hills, even slowly or do you have to pedal too?
I lived north of springfield when I was a kid....so I know about them Missouri hills.....and curves. here in kansas, everything is square & flat.
You should be able to get a 50t sprocket from Mike at http://www.simpsonmotorbikes.com/ . I looked on his site but didn't see them, if you e-mail him or give him a call (# on his home page) I'm sure he can hook you up...Kelly
here's a couple big ones. both would take some work to mount. maybe the 60 tooth could bolt to your existing sprocket? might mess up your chain alignment?
60 tooth.....talk about climbing....you could prolly climb trees!!
Wheelies?...... anybody?..... I know Tom wants to do some wheelies!!
oh you guys....and your need for speed! 8) I ride mostly in town & there's a lot of stop & go. I appreciate the extra take off ya get with bigger sprockets. I'd like to try a 60 tooth on my 55cc. it might only run 20mph but it'd get there quick. naaaa, cause then I'd wanna do some off-roading....& I don't heal up as quick as I used to.
50 tooth is too slow and not worth the increase in stump pulling up steep hills at the expense of top speed.
A 48 tooth sprocket is your best bet. I live in Colorado at 7000 feet altitude. Every combustion engine (piston, jet, turbine) loses 3% horsepower for every 1000 foot increae in altitude. At my altitude, I'm losing 21% of the engine's power. I have found that a 48 tooth sprocket is all I need to climb even the steepest COLORADO hill with ease. I haven't found a hill yet that can't be tackled with a 48 tooth sprocket. A 50 is JUST TOO DARN slow for an 80cc engine that is slow revving to beign with.
BTW, I have climbed mountains with my bike and my 48 tooth sprocket took me all the way up to 12,000 feet in altitude with no problem.
I have some 55T sprockets I need to get posted on the thatsdax.com website. Remind me to get them posted . Not sure of a price yet. I had them milled special on a water jet cutter. anyway..Remind me to get them posted.. Thanks...
A friend of mine has a machine shop and can make ANY size sprocket for our bites (ready to bolt up using the standard 9 hole mounting plate). The sprockets are made out of heat treated 7075 T6 Aluminum for durability and is WAY lighter.....PM me if you are interested....He made me a 40 T sprocket with satin finish and lightening holes for $45.00 ( I tried the 36 T but it didn't pull hills well enough, and the 44 T was way too low a gear for me...I wanted a little speed too!)....
