Right now I have a Yamaha Road Star 1700 and my recently purchased RC51. I’m planning to sell the Yamaha Road Star next year and buy a Harley Davidson Road King. I know I know lots of people think it’s a down grade. I've always wanted a Harley I was raised up on them. I want a bike I can ride for miles and miles. I really like the Road Star but My Ex Wife picked it out and it just brings back bad memories plus I had a front end blow out on it and crashed it I don’t want to put the money into it to fix it up. Anyway once I get the Harley and get it paid off I'm going to buy another sport bike. O yes I will not sell the RC51 I'm in love with it. I drove a ZX6 (636) to day and it felt neutered in the bottom end maybe it’s me but the RC also felt faster overall. However I did not push this bike because it is not mine, so it may be wilder that I realized. I have pushed a GSXR600 however I don’t remember what it was like. This makes me interested in a 1000cc inline 4. I know they are faster in the top end but I'm not interested in ultimate top speed. It makes no difference to me if you bike is faster on the straights or has a higher top speed. It’s going to be about 2 years out so it's kind of too soon to make a decision now on what to buy but if you were going to buy another sport bike right now what would you buy?
