Hi
JC here from Alpinawheelsusa.com
or better known as PAK Bikes.
Let me try and answer a few questions
Here is a chart based on the Aluminum alloy wheel on the Paul Smart
![](http://jcpakbikes.com/alpinawheelweight.jpg)
The GT wheels are a lot heavier then the Alloy
The Alpina's have most of the weight towards the center so when the wheels spin they are lighter.
The static weight loss is not much but these wheels are stronger then forged wheels as they flex more.
Most Supermoto guys like Alpina spoked wheels because the spoke wheels do not crack like forged wheels do whne Bashing about.
Also There is no Carbon Fiber Rims or wheels available for the Monster or the Sort Classic right now.
This wheel from alpina are called the Carbon Matrix Tubeless STS system wheel from Alpina.
The STS System is very Different From the Tubeless-A-System.
The "A" System is only available for the Ducati Monster, Ducati Sport Classic, Honda Hornet and Motoguzzi V11
The STS uses the stock Hubs from the models that these are available for, or in some cases depending of the model Talon or Kite hubs are used. These kits or builds come with the alpina spokes, Alpina STS nipples, and Specially alpina Machined rims made by Excel, GLM or in some cases Behr. The STS wheels are tightened and trued at the rim and sealed with the STS Nipples
The A System has a fixed nipple that seals at he rim and are tightened and trued at the Hub. The hubs are only available from Alpina made from a solid chunk of billet.
The "A" version for the Monster comes in two different rear axle sizes and has a slightly different Hub from the Sport Classic.
The front Wheel Does not have a 4mm Rotor Spacer option as the Sport Classic version does. This 4mm Spacer, when used, will run the stock caliper. When removed the wheel accepts the Brembo Gold like 4 pad or 2 pad Caliper.
They will fit all Monsters that have the standard Swingarm.
I have heard that you can use Stock Sport classic wheels on the monster. It seems that the Axles size and the wheel spacers are what is different.
If I can help in any way or if you have any more questions regarding Alpina wheels please email us directly

Good to know that the change would only necessitate a rotor change for the later 620s & 695.
Thanks for the link. I remember that article which I read when researching new wheels a while back. Just like the author I opted for Carrozzerias from DucPond. I too weighed my wheels before and after. The stock front 3-spoke Monster wheel from my 2005 1000 weighed 10 lbs w/o the rotor. The stock rear weighed in at just under 18lbs w/o the rotor or sprocket. So those GT100 wheels are definitely a lot heavier than stock 3-spoke Monster wheels. Looks like he would add 7.25lbs to the front wheel alone by doing the switch.
I would still like to see the weights of the Alpinas and also the aluminum-rimmed SC1000 and Paul Smart SC wheels.
