I love middleweight bikes. 600-800cc.
The art of happiness is not to ride anything larger so you don't know what you're missing.

I rode my brother's 102 cubic inch Yamaha Warrior and then thought my bike sucked for the next two weeks.

 

man i remember the first time i opened up my zx10. man i was shocked how much power it was

 

fiddiness for sure. time in the saddle for that setup, etc.
