I'm jealous of the 180 tire selection, although on a bike with this HP I'm not sure that's a HUGE advantage. It's obvious on the SV's when you put a larger wheel on - the whole rear assembly ends up heavier and drive out of corners is reduced


You need a lighter rear 180 tire ;). A larger tire is extra weight for sure but the compounds in the 180 are a ton better. Couple that with the larger foot print and you should have all the traction you need.

Traction is great but when you don't have the HP to turn the extra weight it's kind of moot.

The FZ-07 is plenty fast! I love it.

I can't imagine how fun it will be with quality suspension. Watch the kickstand, it will hit the ground easier than you would expect.

I'm curious how wide the motor is down low - do you feel it will be prone to scraping when lowsiding?

The motor is 15 inches at the widest point, same as the SV. The sump on the FZ is very different than the SV though, it hangs much lower. (See pic) The SV sump is between the lower frame butresses, quite protected. The FZ sump sticks down like a orangutan's ass. Speaking of frame, the FZ is much more dainty between the lower rear swinger/frame junction, fingers crossed for strength, hope Yamaha pays for good engineers...

Most modern supersports feature this type of sump and they generally keep their oil inside I guess.

Can and SV not spin the rear with a 160?

I have only been on LW bike once and it was a super bike, so i have very little experience with this.

I know a lot of clubs allow a 180 conversion as SS Legal so they can run better tires and have more selection.

I guess I assumed that a 180 was all around better but maybe that's not the case.

Although the SV (and most other ltwt bikes) have terrific torque characteristics, under normal race conditions you'd be hard pressed to 'spin' the rear unless you are pretty aggressive and twisting it hard and early on the very edge of the tires. Dare I say you'd be asking for it. I guess it would be more a lack of traction than too much throttle/power.

Undressed she tips in @ 325 pounds! I left the bars on for now to hold the controls out of my way, waiting on the frickin UPS/FedEx guys... racers are known for their patience ...

I guess I assumed that a 180 was all around better but maybe that's not the case.

With a fresh set of slicks I can pretty much go WFO on corner exit fairly soon after letting go of the brakes/apex. The DOT's you have to roll on a little more carefully (they are street tires).

At our 5-hour endurance, there was a GP2 team on a SV that chose to run a 180 Dunlop DOT (they never did tell me why) and it was pretty obvious coming out of corners they lacked a little oomph. (I realize there are probably other factors here as well)

At the SV Challenge at VIR this past August, which was a money race held during a WERA weekend based on SuperBike rules, out of the top 10 SV's running, only 1 used a 180 tire (and it was not the winner). The other top 9 were on the 165 slick or a Pirelli 160 (DOT or slick).


**This is not to say the 180 isn't good or better than a 160, I'm just not willing to invest into a GSXR wheel to try it (which would put me into SB rules anyways - where the 165 slick is king).

Dave are you going to try and get a winter/early spring race or track day in somewhere south?
