it goes around 50mph... very hard to control at that speed mostly due to the tires ballooning out.... although that makes it go faster... I only do speed runs in wide open EMPTY flat parking lots... Heed this warning or pay later... for bashing, engine can't be beat... I have no complaints at all about it.. always starts and holds a tune... the cen engine was very good, but this is sooooo much better... I lowered the suspension and am working on fitting street tires to it..
