Re: Riding school
One other thing, the better you learn to ride the more your going to get out of that 620. My 160lb brother on a $30k heavily modified 996 couldnt keep me in sight on the tight stuff when my 300lb butt was on a -50HP $5k KLR 650...
The main reason I would upgrade from your monster would be if you need more for passanger comfort or touring needs. Otherwise buy a filter, jetkit and a nice set of pipes then buy a good shock and get your forks done. Actually do the suspension first, better handling will shave more time off the track than all out power... Well unless your monster doesnt do it for you anymore, they buy what you want.
