The Bridgestone Battlax T32 is serving me well, in the GT spec . . .

Bridgestone says "The "GT Spec" is for heavy weight vehicles" and "can be installed not only on large tourer vehicles but also on medium vehicles around 250kg".

Do you think that the T32 GT spec is better than the standard T32? It does sound hi-zoot, but I ask as the V11 dry weight is around 220kg. I'm looking to replace the Battlax BT023s on my bike.

Half full of fuel, with my basic pannier load-out, mySport is 550 pounds/250 kg. So, I reckon I qualify. The GT is not available in the 160/60 rear I prefer, so I am only running it on the front. I am only on my second GT front, and before that were T31, so any "longer life" remains to be seen.

128,457 / 36 = 3568.25 avg. miles per rear tire ... 128,457 / 26 = 4940.65 avg. miles per front tire

Is this an accurate average for how long your tires last @docc?  more or less ~1 season?

Seems like 1/3 or less than how long they said my Road 5s might last.

 

 

dang, that Docc is a real squid.  Bet he does burnouts in his driveway!

I received the latest issue of Moto Magazine, and there is a comparative test of six tires designed for Sport-Tourism motorcycles, such as the V11;

• Dunlop Roadsmart IV
• Pirelli Angel GT II
• Bridgestone T32
• Metzeler Roadtec 01 SE
• Continental Contiroadattack 4

The test took place at the Goodyear Mireval track in France. It used to be a racing track purchased by Goodyear and transformed into a tire test track for all kind of vehicles. This track has multiple asphalt quality and a "wet" loop.

The testing was conducted with a Yamaha Tracer 9, one of the motorcycle used for a sport-tourism comparative test with the Moto Guzzi V100S, BMW R1250RS, results will come in a separate post.

Each tire sets was ran for two laps on the fast track, length 6.6 km. When the tires are manufactured, they are covered with a thin layer that facilitates their removal from the molding machine;

The braking tests were measured with a VBox Sport from Racelogic, using GPS data.

In the dry, for each tire the speed was set to 125 km/h, and the braking distance measured between 100 km/h until 5 km/h.

In the wet, the set speed is 90 km/h and the braking distance measured between 80 to 5 km/h

Maneuverability was checked; the Goodyear track has all kinds of tests to verify how easy the motorcycle respond to impulses. Also, behavior on wet asphalt such as fast, slow curves, banked curves, skidding under acceleration, stability.

Now we need to keep in mind that the braking results on the Tracer are carried out using the ABS, I don't really know how it translate on our V11.

Find the results of the test herewith:

-The top performance was given to the Dunlop Roadsmart IV, the second best was the Pirelli Angel GTII;

Some of these tires have a GT version for heavier motorcycles and SP for Sport roadsters. I believe the V11 can use the standard version.

Note that all the tires tested are manufactured in Europe and Japon for Bridgestone.

Michelin is the only manufacturer to have dual compound for the front and rear tire. All the rest have dual compound rear tires.

Again, one important aspect of tires is never measured: average autonomy.

I am currently on ROAD 5, since the ROAD 6 were not not in stock. The Roadsmart IV neither earlier this year. Only the Roadsmart III was in stock.

The Roadsmart IV is given as the best in terms of maneuverability and stability.

Something that I have been told; the Tires we purchase in the USA are not coming from Europe. It should not make any difference in terms of quality though...

I am completely happy with my Road 5, and will attempt to install Road 6 at the end of year. Then I will check the Roadsmart IV at the end of 2024.

 

 

I like the Dunlops.  So I was ready to do a Church Lady Dance.  

But it dawned on me that this was done at a Goodyear Test Track and Dunlop is a Goodyear brand.  Despite that -given Guzzi content- still the cheapest!

The Metzeler Sportec are the cheapest you could get at the time I did the pricing survey. Hence, they were sold out.

These were sport touring....sometimes the full on sport tires are "cheaper" because they last half as long.

I can't easily get and price out all the tires but I know the Mich and Pirellis cost a good 20% more.  And all the prices have gone up since I last purchased , Dunlops too.

Summer deal on Bridgestones running now. Good time to get a set for rainy days.
