Thumpstar 125cc Pit Bike Big Wheel Conversion 

That’s sick. Huge difference with those wheels

"take her off road" then proceeds to drive down the street!! LOLOLOLOLOL

That big wheel kit looks pretty damn tough on this bike...I bought the 2022 model for my kid..its small wheel. But seems solid

Back wheel must rub the undertail or hit the shock when you hit a jump or wheelie

Aye it looks good! I’m doing this to my girls bike and was questioning the 17” front wheel mostly because I have a oil cooler mounted but I think I can make clearance hopefully.

Hey man how did you get around the 20mm axles I can’t find and wheels bigger than 15mm

I have a problem with mine, I have an M2R KXF125, I put a big wheel pit on but the wheel hits the engine when the front wheel hits the floor and it’s annoying asf cuz it’s slowly damaging the tires

For the front how can I go from a 12 inch tire to 14 . Do I need just a new brake kit ?

Hey man I hope you see this because I want to do it to mine all the wheels I see are 15mm bearing and Thumpstar takes 20 how did you get past that

Did you run into problems with the rear wheel spacers?

Thx a huge bunch

What frame is that?

Did you ever run into any rear tire rubbing issues yet?

can i install 18 inch both wheel on thumbster 200cc ?

Says 107 because it's a 107cc bore

put a helmet and goggles on for that wtf.
