Short rear tire life. - I blame the shock.

Recalled tire life:
1st tire: 2,600 miles
2nd tire: 1,500 miles
3rd tire: 1,500 miles

Yes, I'm hard of tires as I test the adhesion qualities of every tire. That noted, I have routinely gotten 3,500 to 6,000 miles out of tires on a number of street bikes. All heavier and more available power.

So, I have to look for a different variable. In addition to the obvious benefits of high performance suspension I'm expecting increased tire life. The thought is that by keeping the rear tire better connected with the pavement surface will yield longer tread life.

much easier - adjust your ridingbehaviour :D
 
I'd like to blame the shock, but in reality its my fault being 18 stone and giving it full welly everywhere...
 
It's full acceleration and compression braking. That said, it's the way I ride every bike. Coming from much heavier bikes, I expected at least the same tire life, maybe more.

I'll look for tire photos.

I do tend to replace tires as the wear bar is approached, not wanting to tempt fate when riding in the wet.

The other issue is the road surfaces. With most of the miles in the Ozarks the roads are resurfaced with Chip & Seal. The little stones used as the chip are very abrasive.

Are you still using the Scorpions? I hear a lot of good talk about the newer generation of "sport/touring" tires. Dual compound, and sticky enough on the sides to drag hard parts in the turns.
Sorry I don't have any personal feedback on this, but I will be in the market by the end of this year.

No worn tire photo.

Now: Pirelli Diablo Rosso III - Dream tire for street.

Yes, we ride high and low, fast and slow, but the common denominator is that we ride twisty roads. Twisty backroads that seem to wear tires quickly.

The new Mopo AB-1 is installed. 3 way adjustable. High speed and low speed dampening and rebound. My expectation is to be able now get 3,500 mile tire life.

Nothing unusual about the tire wear. Seems to be fairly even.

I tried to find a photo of the Bridgestone T30 evo rear I had on mine last time, but was unable to. It was just barely showing the cords in the center, but still not quite to the wear bars at the sides of center. Was a very unusual wear pattern, but I suppose it happened from all of the slabbing that I do.

Out of curiosity, any photos of the new suspenders? They definitely look the part.
 
Not photos of the bike yet as it is still with the installer. Soon though.
 
Just curious about the front. Did you replace the front with the matching tire each time? My experience has one front to two rears.
 
I always change both front and read. Especially as I try different tires each time.

If I stick with the Diablo Rosso III there is the option to just replace the rear tire. When I've tried that in the past it seemed that hard braking and lots of corners caused uneven front tire wear. So, while there was still front tire tread left the odd wear made me wish I had changed both at the same time.

Tires are such a safety item because we only have two wheels. I always start long rides with fresh meat. Want the best adhesion possible.

Since I no longer ride across the country, tires are used only for the focus of the ride. This makes new tire purchases more affordable.

Carrying the Hyperstrada on the back of my car allows me to take it with me when traveling to more places. Miles on the car are irrelevant anyway.

Question about your bike carrier- did you add airbags or other suspension mods to your 4Runner? Looks like it's running nice and level despite having 500 pounds or so hanging off the hitch.

Yes, 4 Wheel Parts added the Firestone Ride-Rite airbags. This allows me to adjust the air pressure for various loads. Because of the modified suspension, I have different airbags than the catalog says. 4 Wheel Parts because of the warranty. I adjust the loaded level with a measuring tape.

Interesting all the occasions I find motorists taking photos of the white Hyperstrada hanging on the back of the white 4Runner.

I now have a 1,500 lb capacity drop hitch, which allows the Hyperstrada to be carried 8" lower. So easy to load and unload by myself.

RSL, how are you collecting the data points for the graphs you show? I am looking at the DDA and was thinking of a dashcam to collect the gps coordinates.

Track data is archived automatically by Garmin Zumo products. Track files are uploaded into Basecamp, combined, fixing any discrepancies and portrayed as graphs. I fix views in Photoshop.

As you can see, the track files save a lot more than just location dots. It's this information that makes for interesting comparisons.

How is the twisty roads data represented? Here is why I am asking: I work for a company called Splunk>. It is all about the data and making it usable. My hope was to get data from the bike. Stuff like throttle position, rpm, engine temp and such. Then marry that data based on time with the gps, alt and such. I want to Splunk it! That said, I am looking for anyway to get data. How large are the files you are looking at?

GPX files

Each ride appears to be 10 to 11 mb.

Track information looks like this:

I was going to ask for a sample of the data. Now I see how the curvy factor is represented in the data. Thanks for showing me the data. I need to see if the cheaper Garmin GPS will save the same data. Again thanks!
