Wow looking great and your the INNOVATOR now with that Classic 17" front on a R3T besides that Triumph America Quick Release Summer screen that clips straight on/off just like your original big screen did.

If that is a 130 17 how does it compare overall diameter wise to stock 16". 130 is a big change from the stock 150 usually fitted to the 17" rim.

Tacoma is a good place to check for car and motorcycle tires wheel combos.

4.8% is a big difference from stock which increases steering response a lot and risk of grinding parts that may also cause a crash by taking loads of tires when cornering

Well done you clever innovator! When compared to the stock R3T 150/80-16 though, they are a close diameter match with benefits of narrower and better speed ratings.

Wow that 130/70 is back to the -5% diameter size from your stock 16" front, she will be steering a lot sharper now that is for sure!

Don't go road racing on them curves though or your foot-boards may hang up, but ........I do have spares for yuz all!

I just had to buy a floor board because i dropped it last weekend in a gas station parking lot, stupid mistake, anyway no further details, It definitely handles better with the 130, the stock 150 is a slug, the goldwings, the challengers the hogs are rocking 130s be alot of bias ply but still the 130 carves much better, i just need radial so the weight rating is not as high as those bias ply settups.

I admire your tenacity....

i will think of you and twist it.

Said the same thing as a teen to my friends gorgeous older sister. That is not a day I like to remember. I got my butt kicked by both at the same time.

I find this tire-talk very intriguing. The original Rocket Roadster sat on a reverse dago where the front axle sat ½" higher than the rear axle.
Back in 2012 When I went to a 240/ 55R 16 rear & 140/75R75 front the rear axle was placed ½" taller than the front axle. This reduced trail and hugely improved handling. Later I discovered the Michelin Road 5 (now 6) 150/70R17 rear tire. I run this tire on front backwards and my world was changed once more. What a tire, what grab while dragin' my Standard boards all way 'round a twisty! I found the wider 150 aspect ratio to work better with the wide 240 rear tire.
I understand wanting "level" axles, but at real high speeds won't this bring less front end stability?

With the 130/70/17 and 200/55/16 im 1/4 lower in front, im fixing to install the 130/70/16 for testing and it should make front 1/2 lower than rear but i was wanting this for dragstrip. I have fork height set to stock for all this tire testing. I have run the forks a 1/4 in up in trees and that seemed to help the 150 front handling. Ive not done this lsr racing so im gonna be on a fast learning curve. On the drag strip i like the front end lower as i think it helps with launching. Again all a learning curve as i cant speak to experience as i have none. But im gonna make experiences and hold on tight. I will know more when i can get the bike above 130 or so, i am taking barbie steps with this testing thing 100ish feels great with the 130/70/17 and 200/55/16. We will be hitting local drag strips over the next 5 weeks to figure out more.

My forks are 1/4" up in the tree, and I intend to put them back down. I wonder if it has to do with the high speed weave I was getting. Since I took the bags off I haven't seen it, but I've only been to 120 or so, I'd want to hit 130 or 135 to feel sure it's gone. I live in the flatlands now anyway, what am I going to do with quicker steering? Something you might want to experiment with before your high speed runs.
