300ft dirt drag racing gearing “ starting Point “

Recommended Posts

Hi gents 

The bike has stock frame  has 10mill Trex on alky. 22x11x8 14 Extreme Paddles and current gearing 16/43 and +8 swingarm. My weight is 188lbs. It runs consistent 4.1sec in 300ft. Not sure if it is good or bad :)

Any recommendations on gearing? 

Should I start from stock gearing then slowly changing the rear and front sprockets?

What RO are your rear tires? On my 10cub i ran 15t front and 42/43rear for 300’ track with 14paddle stg. (78RO. )I weighed about the same as you do. Bike weighed 280ish race ready. Ran 3.9s very consistent.

I bought them 15 years ago. I barley see the 22/11/8 extreme SLS. The rollout is 7X 

How can I check the R/O? 

I still believe 16/43 is too tall 

I believe 10mill cubs still would outform my KT 10mill Trex :)

To check your ro either pull tire off quad, or jack rear of quad in the air. Run your desired air pressure and use a tape measure(i use a small 1/4”wide stanly steel tape) and measure the circumference of the center of the tire.
