My 2007 450R with HRC kit will run around 85mph
at least 100
121mph or 187kphthere is no way in hell dude.! you probably have one and lost to a Banshee and now you walk around wishing your quad would do 121mph.. get a life!!!!the max speed of a stock TRX 450r is +-86mph (140)
same as the trx 450
75 miles an hour is the top speed of a 2013 honda trx 400x
