Has anyone tried a 180/55 rear tire in lieu of the stock 190/50, by chance? I ran that size on both my Speed Triple and 950SM -- both of which have the same size wheel as our FZ-10s -- and I was always happy with the results.
The advantage I see is that a 180/55 is 180*.55 = 99 mm tall, rather than 190*.5 = 95 mm tall. So, the rear ends up a touch higher, which would likely improve steering.
Thoughts?

Most 180/55-17 tires are better suited to 5.5" wheels, the MT/FZ10 comes stock with a 190/55-17 not 50 aspect ratio tire, you can run a 180/55-17 according to some manufacturers(tire) websites but most recommend a 190 size tire on the 6" rear wheel of the FZ. I know my friend who had a Ninja 1000 with a 6" wheel ran 180/55-17 tires a lot it should quicken the steering some with a narrower tire, but you also flatten the profile some by mounting a 180 tire designed for 5.5" wheels on a 6" wheel. I had three sets of 120/180 tires when my bike needed a rear tire and I went with a 190/55-17 rear instead of a 180 because I liked the steering response of the stock tires. Even among tires of the same size but made by different manufacturers, there will be differences in circumference, often times racer or track day riders will have to make ride height adjustments for this very reason because of the differences in ride height of similar sized tire of different brands. A street rider probably won't notice differences as much because even the fastest street riders rarely approach a pace close to that of a racer or fast track rider, because even though we may like a fast paced ride every now and then, running at the limit on the street, the risks can be high if you crash.

I've decided when the time comes though to take a look at these new ones, I've had amazing results in the past with their tires. New Metzlers model RR.

If you go smaller or bigger you'll play havoc with the traction control. People over here on the UK sites have tried a 200 on the rear and the TCS kicks in making it unrideable. But I suppose you can always turn the TCS off!

Why not go with a 190/55? And as for the TC, I dont think there is an issue. Reading up on how the system works, it is based off wheel speed and output shaft speed, all compared together. The system on my old ZX10 was similar and I ran 200s all the time and it was fine. But hey, maybe so. I have a set of 200s on order, so I will let you all know!
Also, liability wise, a company would not release a product that will only work with one tire.

The profile of 180 means it will be being stretched over a rim designed for a 190. The profile or peak of the tyre as it were will therefore be shallower than the tyre manufacturer intended and change it's handling characteristics. With a less peaky profile the bike won't turn into the corners as well due to the reduced "cone" effect.
This will also effect the TCS as the 55 height will be reduced as the tyre is stretched to fit the rim. This reduces the overall radius of the tyre which is one way it will cause the TCS to come in. This is effectively like changing the gearing as the rear wheel will now be rotating faster at the same speed and the bike will see this as slippage causing the TCS to kick in. The bike will also sit lower in turn changing the rake and swing arm angle.
TCS basically sets parameters and monitors the difference in front and rear wheel speeds. Changing the diameter of the wheel even by a fraction will cause the wheels rotate at a different speed to that set thus and outside these parameters.
The difference may seem so small but think Of the difference you get by changing just one tooth on a rear sprocket. Or, the difference of changing the steering rake by just 1°. You may think the change is negligible but you're changing the tyre width 5% from spec.
To also demonstrate how sensitive the TCS try popping a wheelie in TCS 3. You'll kangaroo up the road because as soon as the front lifts the front wheel begins to naturally slow. The bike only gets about 3" off the ground before the reduced speed is sensed by the TCS and the bike thinks your in a slide so cuts the power. As soon as the front hits the ground again and the speed of the wheel is back to normal you get full power and the front lifts again. Thus wheel speed of the front slowing is minimal but the bike sees it really quickly. Of course TCS 2 and 3 have wider parameters but the principle is the same.
You may not have any issues but experience from people who have gone the other way by fitting a 200 indicates you will.
Be interested to see how you get on.

I just realized the whole premise of my first post was wrong. Our bikes' stock rear tires are 190/55, not 190/50, as I thought!  Given that, I see no reason to switch to a 180/55, which would drop the rear a few mm. |

I just picked up my 200s, I will report back when I get them on.

For sure. I have the stock tires on now, I'm going to the track for 2 days next weekend. I think I will change after the first day, I don't see the 'stones lasting, ha.

If the TSC is that sensitive, wouldn't wearing a new tire down to the bars cause issues? It doesnt and that's at least 5mm shorter.

I took the 180 off. It gave the bike lazy turn in and vague feel. Its also imparted an odd off-center feel. Not recommended but no issues with TC.

I think our bike would have benefitted from a 180/55 from the factory, with a proper 5.5" wheel. Less weight, and better handling. To me, that size is the best compromise for 150 HP. Wider is not always better IMO. But slapping a 180/55 tire on a 6" wheel would actually be detrimental IMO, as many others noted above. But with relatively wide handlebars, I have no complaints with the 190/55 tire, especially with the more triangular Road5s I just slapped on my bike. Feels really flickable.

I'm always amazed at how many people know so much more than the manufacturers. I think you should all get together and start your own motorcycle brand. It'll definitely be better than these hacks at Yamaha.

Exactly—it isn’t a high end TC system and it’s a hell of a bike with all that turned off. Everyone worried about it just hold down the TC button forwards for a few seconds in neutral just after starting the bike....you’ll never go back! |
