J6G1Z:
Just for the "Trick" factor. LOL!

cdntfindanAscot:
Cool! I was hoping to do something similar with the front end on my VT. do you know if the triples are the same on both ascots?(the thumper and the twin).
cheers

That I don't know. I haven't had a VT in front of me in a long time.

FT500R:
I might be getting a second FT to turn into a classic racer.
I am looking at the Hurricane swap but am in doubt due to the difficult tire size.
What is your experience so far? Can you get any decent tires for it?
Did you manage to fit the 160 or did you have to go narrower?

regards,
Paul

I'm running Hurricane wheels, forks, and front brakes on the FT500 (which I am selling:
 https://portland.craigslist.org/mlt/mcy/d/portland-1982-honda-ft500-ascot/7119399351.html).

Bought it as a rolling basket.  To move it around the shop, and on initial shakedown rides, I ran take-off Dunlop radials from a friend's RC390 KTM.  I don't recall the exact sizes but I believe ~100 up front and ~130 in the back. 

I ended up swapping the radials for BT45 Bridgestone bias plys because they're 'taller', with a lot more sidewall than the radials.  The extra height means a lot more ground clearance.  You're already losing at least a half-inch of ground clearance with the smaller-diameter wheels, plus I believe the Hurricane forks are shorter than the stockers, too.  I made up for that somewhat by dropping the forks low into the triples and buying slightly longer Hagons.  I didn't go so far as to fit rearsets, which would help.

I've run the BT45s on a number of bikes, they're good.  They wear well, with good traction.  I've done a few 'track days' at a large (~0.6 mile) go-kart track just south of me with the tires; good laptimes, dragging knees and pegs with confidence.

Below are my notes from researching tires back in 2017.  Please bear in mind things may have changed since then!

FT/Hurricane:  2.5" front wheel, 3.5" rear wheel
Michelin OKs, for that wheel size:  110/80 bias, 130/80 bias
Bridgestone BT45s, for that wheel size:  100/80 or 110/80 bias, 130/90 or 140/80 bias
Conti Twist SM / Sport SM offers: 100/80 bias, 130/70 bias
Avon OKs, for that wheel size: 
   -- AM22 race:  110/80 (Medium or Soft) bias
   -- AM23 race:  130/80 (rec is 3.0 but OK'd for 3.5) bias
   -- Streetrunner:  130/70 bias
   -- Roadrider:  100/80 bias, 130/70 bias
