My first bike was a 1000.
before that I had just rode quads which is a whole different animal.
At first I took it super slow and had a hard time laying it over to turn.........after riding a couple months I was a pro........and 600 feel small and flimsy.......
At the time I didn't know what I was getting into.........after I bought it and researched it I loved what it was..........a TL1000R..........rare sport v twin with a distinctively exhaust note..........I don't think I'll ever sell it.........but I'm thinking of buying an R1.
