I'v ridden both. My friend has the Suzuki. They both are really similar, but the Yamaha pulled better down low. I liked the handling of the Yamaha better too. I dunno, you really have to try them both. I do think, with these too it'd come down to personal prefrence.

Btw, why aren't you considering Honda?

CBR600RR

I like the Yamaha R6. I have liked it ever since they introduced it. I've never ridden it nor have I ridden a motorcycle since a Kawasaki ZX-9R about 6 years ago but I really like the looks and design of the R6. FWIW, the rags all rave about it. To totally superficial and rating them on a cool factor, the R6S is way tricker looking.

I'm a little surprised the wife is giving you the on this.

Depends what kind of riding you like to do! I have a gsx-r750, love the way they ride, but as far as quality goes i think yamaha wins that one! I rode a friends kawaski zx-6rr and that little f***ing thing has plenty of power down low and handled like a gem! Goodluck with the purchase and ride safe

completely comes down to price and availability and also preference for looks. The Honda is also just tad more expensive but the performance is still on par with the 2 cheaper bikes... less $$ for same performance = winner..

if ya don't mind me asking, what are ur specs (height, weight, ect.)?

what's the difference between the Yamaha YZF-R6 and the Yamaha YZH-R6S? just the name?

Didnt check the specs but probably just a little weight savings, engine and suspension tuning due to the S in R6S like kawasaki with the zx-636r and the zx-6rr. A trackday version i'm sure.

Dont know about SANguru but i'm 6'2 and a good 210pounds if not more and it does get a little cramped behind the screen! I'm thinking harley or maybe a chopper as a next bike if i can afford it!

the reason i asked about his size is because if he's close to ur size, i think he might get bored w/ the 600. i'm about 5'9 165 and i had an R1. prior to tahat i had a Ninja ZX7-R.
a friend of mine, roughly ur size, didn't take my advice and bought a 600. w/in 1 month he was ready for a bigger cc bike.

my choice would be the honda also... much more comfortable on my back with longer rides. i had a cbr600 a loooooong time ago and it was the most comfortable one to ride.

i say splurge a little and get what fits you the best.

As far has handling/dynamics goes, I think the Honda is the best of the three. It's EXTREMELY responsive and balanced, and is pretty smooth at the same time. There's more to a bike than the engine.
