I've done alot of shopping with both Rocky Mountain and Motosports... i mean ALOT!! To the tune of over $1000 a year at both places some years.. mostly motorcycle stuff...but lately i have compared prices on BikeBandit.com and shopthumpertalk.com, and they have a 110% lowest price guarantee. I havent gotten around to compareing prices with MotoSports or RockyMtn yet, but by looking at thier prices i would be willing to bet that they both would beat either MSports Or RockyMtn. and if they cant then at least one of them has the 110% guarantee. They are worth a look. Also both BikeBandit and thumpertalk have OEM parts as cheap as you can find them. By the way, i put some Dunlops on mine a year ago...damn things are worn out already..DON'T BUY DUNLOP!!
