Sprocket Size

[Sidewinder Jerry]

I have lots of hills too. I just keep wondering about the acceleration and torque advantages of the 48t, but mostly about what my rpms would be cruising at 20-25


I feel like it would make sense that with a slightly larger sprocket I could do 20-25 no problem with a crap ton of torque.

With the 48t, you'd need to do 6361 rpm to do 25 mph. Meaning you'd need performance mods to your engine for this to be your cruising speed.

With mods that'll yield 8000 rpm, your top speed would be a little over 31 mph using a 48t sprocket.

Well, this actually sounds fine. I really don't need to go fast at all. If it's too slow I'll buy a 44t.

Without mods, he would have to be at WOT almost all the time, how long do you think his motor would last having to ride at WOT all the time???

I wouldn't be at WOT, as I really just don't need to go fast. Idk. I could probably email them and have them change it to a 44t if you all think I really should.

@Chainlube said is WOT is close to 40, so I could assume my WOT would be close to 30... ?

Exactly, with no mods and a 48t 5089 rpm would give you a 20 mph speed.

He wasn't talking about using a 48t sprocket doing 40 at WOT.

That is a good cruising rpm for a tiny 2t.

Exactly. I feel that cruising around 4500 rpms for a 2 stroke would be just right, to have plenty of oil and not carbon up.
