Have been thinking for a long time to fix a bigger rear tire after reading some forum threads and counting on the benefits, now it's in place!

100/90-17 instead of the original 100/70/17 was maximum dimension that fits under the rear fender.

- 4 cm bigger diameter

- 7% less rev/km

 

- Will take me 12 cm longer for each rev of the motor!

- Can get me some better top speed and longer range, + a less inaccurate speedometer (TS shows 14% too much as stock) will start testing…

Why did you not go wider. I don't like the look of the bike with these skinny tires. I'm planning on doing something like 130/70/17, but not sure if it fits. How much room do you have left depth wise. And not even sure if it will fir on the rim or not.

Regarding the circumference:

100 * 90% = 90mm

130 * 70% = 91mm

ps. small typo in your message: standard is 100/70/17

I'm also thinking in changing the tyres to 130/70 to the rear and 100/80 to the front and I found the Continental ContiTwist Sport in this size, I am really exited how will the change effect the behavior of the ride

I also think the standard wheels looks too skinny, and 130 width was on my wish list, but short answer is that it will not fit without modifications, has seen TC:s with bigger tires, and there is an option to made new plates for the rear axle and move the whole wheel backwards.

But even with same width there is more rubber visible now and the overall look is some better.

There just some mm between the rear fender and the tire now, will try to move it some more from the tires tomorrow.

@gyorgy, what dimensions did you order?

100/80 for the front will definately need some modifications to the front fender or??

 

@Super-Honda, yeah that rear fender is tight... If you push from the top down a little it will become slightly wider enabling to fit the tire. I can't find any 130/65 tires but 130/60 is available like the Heidenau K68, that one isn't available for the front though, so you would have to be running 2 different tires. These are the ones I'm currently eyeballing:

  • Continental ContiGo
  • Pirelli Angel CiTy (only 120/70 rear)
  • Micheline Pilot Street (only 80/90 front)
  • Metzler Sportec Street (only 80/90 front)
  • Heidenau K66
  • Heidenau K80 (more expensive)
  • Heidenau K68 (only 130/60 rear tire available)

The 130 wide is my biggest desire, maybe the 130/60 K68 will be pretty badass looking, I don't want a bigger tire, just wider and the small the height the wider the tire will look. I also like the pattern and they should perform ok.

I'm definitely looking to upgrade the tires a bit, but I am avoiding messing with the hub, and therefore am not looking to replace the rims. How are they fitting wider tires on the rim? Am I missing something or is the width just the width, and you can only influence the ratio for a thicker boi. 
I have the TC, is it really any easier for me to get a bigger rubber? And btw, does anyone know where I can get extensions for the back tire/axel? I'm almost considering a new rear "fork" to get a bit more length, but of course, that means more cost. I don't have the stuff here for much machining, as I've moved internationally and just have the basic tools
