Anybody put 190 race takeoffson their bike for track days? Only reason I'm interested is because there are way more 190's available than 180's.

 

190 will mount to a 5.5" rim, but you won't be happy. The profile gets distorted and hanling is compromised.

 

dude post up on the WERA board that you want to buy some take-offs, I can't imagine it being difficult to find 180 take-offs

 

wont catch a 190 on my 600 lol

 

Thanks for the replies,I was just wondering if anybody tried it.I can find 180's locally, just not as many as 190's.AFAIK all the newer 600 racebikes run 190's but 180'smight be better for me anyways because they come off lower hp bikes.

 

If you are in need for more hook up on a 600 than a sticky 180 will give you, you are damn fast. Thats why you still get a 180 on any stock 600 and because they turn a liitle quicker.

 

Here's an article about this:

Does Size Matter
Squeezing a wide tire onto a narrow rim can be a big mistake. Here's why.
By Andrew Trevitt

Those low-profile 190-series tires sure look gnarly on the back of a sportbike, and we've seen them pinched onto all sizes of rims. But in reality, a 190/50-17 fits properly only on a 6.0-inch rim, and cramming it onto anything smaller severely changes its profile.
As an experiment, we mounted a 190-series Metzeler Rennsport onto our F4i's 5.5-inch rear wheel and took some measurements. Compared to the correctly sized tire on the same rim, the 190's profile closely matches the 180's near the edges of the tread, but is much lower in the center area-equivalent to about a 6mm change in ride height. Effectively, the wider tire will give more rake and trail when the bike is vertical, while keeping close to the original geometry when the bike is leaned over. Accounting for one (by changing ride height) will unduly affect the other.
Following our test with the Metzeler Sportecs, we slipped a 190/50 rear Sportec onto the F4i and rode a portion of the test loop for a practical comparison. With no changes to suspension or geometry, the F4i felt substantially different with the wider tire. With the bike straight up and down, steering was slightly sluggish in comparison, but just off vertical, the F4i was quite tippy and darted into corners. The light, neutral steering of the Sportecs was completely changed and the bike lost its balanced feel. The sensation was very much like riding on a tire squared off from too many freeway miles. At higher lean angles, performance was less affected, although making transitions from side to side was unpredictable. And, contrary to the popular myth that the wider tire puts down a bigger footprint and gives more traction, we felt no improvement in that department from the properly sized tire.
We've experienced similar changes with a 180-series tire on a 5.0-inch rim meant for a 170-series bun. Tire engineers work hard to design and match front and rear profiles for characteristics that we sometimes take for granted. Upsetting that balance is surprisingly easy and you should think twice before sacrificing your tire's performance for appearance's sake. "

 

I think I've read that before. Its interesting sometimes how we experiment to go back to what's tried and tested.

 

Matters what brand and tire you want
i'd love to get rid of my takeoff but they're 165 slicks (i race an F3)
you cant get 180 bridgestone slicks
everything else though, good luck. try to buy from someone fast though (not me). Slower guys like me tend ride the tires till there is almost no grip left riding even at trackday level.

and as said before it will effect your handling greatly in the negative form. turn in might feel better if you have a truck tire on there [:'(]

 

take-offs? you mean for drag racing?
