Front Drive Sprocket Size

[DaveenBavari]

Are there any bigger front drive sprockets that I can buy to get even more speed out of my bike. I already have a 28 tooth rear Sprocket and I can only do 35 before I hit the top of the rev range.

You will go faster with a larger than 28 tooth rear Sprocket.
How fast did your bike go with the stock 44? tooth sprocket?

You are overgeared for the puny hp of your motor.
Gearing your bike for more speed will make it even slower.

Post a pic of your piece of junk. lol What motor mods do you have?

You need a tachometer and some common sense.

most motors rub the chain against the cover as it goes around that sprocket - I doubt a simple way could be found to enlarge it

Would a smaller drive sprocket with a matching smaller rear stop that rubbing?

I believe it is possible to have a larger drive sprocket for more speed, you would have to modify the casing first to allow the chain to clear. That would be easy.

To my knowledge there is no prior work on this to provide a purchaseable 11t+ drive sprocket on the same spindle however.

Entirely possible and yes that will increase your top speed if you were to find one that fits.
Post a link to the product below if you find it.

the cover can be cut back a bit to stop rubbing, but since it carries the entire force of the clutch spring to disengage the clutch, I wouldn't modify it too much

There is an 11 tooth sprocket made.

I think he means enlarging the case that holds the sprocket, you know the clutch arm cover.

A smaller sprocket would be less prone to get caught?
