88' Austone taxi tire and 90' rim upgrade

Postby gordonv » Sat May 09, 2015 11:22 pm



Hi guys, thought I would share this with others.

When I bought my bike, I bought a set of mounted tires, so I could have a mounted set ready for when I needed it. No problem with the front, but when I went to install my rear tire, I found that the 92' rim and my 88'-89' stock was not compatible.

I used the rear 5 pin flange that came with my new set, which works with the bikes drive. But I couldn't use the newer rotor and dust cover. The rotor was larger, so I swapped it out with the 88'. I needed to buy an 90'-00' dust cover, to seal the rear drive.

2 years later, I bought a second newer rear rim, a 90' metal valve stem, and an Austone Taxi car tire. Today I mounted them on my bike. I also had bought an 90'-00' rear brake bracket, to mate to the larger diameter 90'-00' rotor, using the stock caliper. I removed the caliper from the 88' bracket, and when putting the rear back together, the caliper bolted right up to the newer bracket.

So now I have the newer rim with larger diameter rotor, which I expect will give better stopping leverage than the 88'. A CT which I notice as no different than the E3 that was on the bike before, in the short 1/2 hr drive I took from low to fast speed. As reported by others, I now have the RPM of what used to be 70 MPH, but I'm traveling at 75 MPH. So I can either now save gas, or drive faster.

Welcome to the Darkside gordonv, after about 800km the Austone tire should be " broken in" adjust the air pressure 2lbs at a time till you find the sweet spot. For me it was at 48 psi. I got 40,000 hard km. Out of my Austone, the taller tire did lower the rpm but there was no measurable difference in fuel consumption. Roll on acceleration is a bit slower. Grip on both wet and dry roads is way better than a MT. If you hear any rubbing on big bumps or when riding 2 up, just move the plastic inner fender forward with a zip tie. I had zero issues with the Austone other than availability here in Canada. I am now running the General tire AltimaxHP 195-55-16
New General Tire 195-55-16 next to the worn out Austone 175R16

Nice bit of info on the new wheel and rotor / brake mount. 8-)
Ride safe, Todd

Ah, then that is why the bike felt like the steering was a little loose. I need to mess with the tire pressure. I know that the front was fine, as I only messed with the rear.

I need to see what I have the pressure at, and then most likely increase it.

Being in Richmond, the border is just 30 min drive away, and the mail houses are right there. I bought mine when Universal had free shipping a little earlier in the year, and before the exchange went up.

I checked my tire pressure, it was at 44 psi. I jumped it up to 50 psi, and took a day off work so I could go out for a quick drive. Jumped on the bike early morning and went out against the rush hour traffic and headed out to Hope for a quick breakfast and back.

Ride felt nice, tire felt smooth. Road was dry and the working modulator I think kept the worst away.

Filled the tank up and a 100 miles there at 70MPH 3K rpm, and I topped it up with 9.5L. Eat, and then right back home driving at 75MPH which was about 3.2K rpm, and to the same gas station, same 100 miles and 10.5L . Lets say 100 miles @ 10L avrg, so 10miles/L. I used to consistently get 8miles/L .

I'm going on a 3K miles trip next month to the VRCC annual Inzane Rally in the Black Hills, and will see what kind of mileage I get and if it holds or not. My best was riding last year at 90MPH and I got 12m/L.

Hey Gordonv,

I put the ATT on my 93 without really ever riding it on the old E3's.
Love it, presently running it at 45 psi. Any lower and I get a high speed weave @>80 mph.

Also put a rear Pilot Activ on the front for longer wear. DD DD.

Sure wish I could meet you at Inzane. I have work managers coming to visit that week and have to squire them around, no getting out of it. Missed last year's Inzane too (had two new hires to indoctrinate), and it was practically in my backyard.
When all else fails, RTFM!

I'll keep the double darkside in mind. Will go that way when I need a new tire, but I figure I'm still around 75% after putting it on 2+ yrs ago.

Inzane, to my understanding, will be the closest to the West Coast it ever has, so I can't miss it. My wishes are with the Valkyrie, wrote mine off into the side of a semi that had cut me off, so went to a convertible for daily driving. My 88' GW costs about 1/8th of regular car insurance, but pleasure driving only.
