RnR have now available NO FLAT Tires...designed for the new R10 onlt....axle hole will NOT fit the older RED karts like I have as replacements ..

the R&R kart is ok & does the job...but really needs to be redesigned ...

Gruvgear has the right idea & "SEEMS TO BE IN TOUCH WITH REALITY"
....AT ANY PRICE YOUR BACK WILL THANK YOU not using a kart like I see so many is just not good..
