Sprocket Size

[DAMIEN1307]

So a 44t sprocket will be plenty enough torque with a Zeda 80?

You also like to cruise at a higher speed, and have a much more powerful engine... Which does make a difference.

My results with my Zeda 80 were quite similar to what I got right now...I still cruise at between 30 to 35 MPH...The only real advantage I have with the Phantom is much more low end torque at start and better hill climbing ability.

I prefer the 44t over anything else, if my kits come with a 36t, I buy a 44. All those engine I use are 80 type engines.

So your RPM cruising around at 20-25ish isn't too low then?

I cruise 25-30 with burst to 40. I don't have any issues with the 44t. YMMV.

Makes sense. Have you ever used a 48 tooth sprocket?

No. 36 & 40 but keep going back to the 44, too many hills around here.

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.

Also, if I hate the sprocket I get, I could always just buy a different one.

Bought a Zeda 80 kit, with a 48t sprocket so now I don't have a choice lol. I don't think it will be bad at all with my lack of wanting to go fast. I also got the dual pull brake handle. Plus 10% off the whole order with a coupon I scrounged up online.

Sidewinder Speed Formula

(ERPM × Wheel Diameter × π)
÷(1056 × Total Reduction)= MPH

The China girl's internal reduction is 4.1\1 (82\20).

Many stock engines have a 10t Drive sprocket and do around 6000 rpm. Performance mod engines can do 8000+ rpm.

Example:

(6000 × 26 × π)÷(1056 × 4.1 × 4.4)=25.726103921

Top speed of a little over 25 mph
