Weighed a few different makes of wheels recently and thought someone may be interested in the results so far.
All same size wheels, diameter and rim width, and all without disc's but with bearings etc and sprocket on the rear.

Antera ...................................Front 6kg Rear 8.95kg
BST carbon.............................Front 2.95kg Rear 5 kg
Dymag 7 spoke forged alloy.....Front 3.45kg rear 5.9kg
Dymag carbon........................Front 2.75kg rear 4.75kg.

Obviously I have bought these for scientific reasons !! Very Happy

Interesting thing for me was the fact that the carbon dymags were lighter than BST's but not surprising as BST's have large alloy hubs.

Jeez, I cannot believe the difference. Surely to save 7/8kg bimota should have fitted these as standard. They fitted fully self supporting CF seat unit after all, that must have cost them an not saved the 7/8kg.
Anyhow, as I have never bought a set, which is the best quality an secondly value for money.
Cheers Vort, Good research

I'd say best value would be forged aluminium or magnesium. They're cheaper to buy new and will give a good reduction in weight

I have a ton of experience with the BST's, including evaluating them head to head with OZ Mag racing wheels.

Here's what happens, when you put a weight on a string and spin it around your hand, the longer the string, the heavier that weight effectively is.

BST's concentrate all of their weight in the hub, head to head with mag wheels it's not even close, even when the mags are slightly lighter. The mag wheel has a relatively uniform weight distribution.

The other huge advantage is that mag wheels bend frequently when you hit tough road surfaces. Race bikes bend them usually across curbs. BST's won't bend at all, they still can fail of course, any wheel can, but they maintain their shape.

Most importantly, you can mail your BST wheels back to the factory for rim replacement, which they do quickly and effectively at a reasonable price.

I stopped using Mag wheels in favor of the BST's, but if I were set on using a Mag wheel again (or even aluminum), I would use the MFR's:

MFR is Marchesini, after he sold his business to Brembo, his non-compete eventually expired and he started MFR. The wheels are the highest quality.

I've heard people say that the BSTs can make a bike feel a bit "flighty". I think that once you'd re-calibrated, they would transform a relatively light bike like the V-due. As far as why didn't Bimota fit light wheels as standard, I think the answer is that some corners had to be cut if the selling price on such small volume production was going to be faintly tolerable. The BSTs are beautifully made and worth the premium over the cost of other light-weight wheels. They are extremely tough and can be effectively repaired, assuming they're not seriously smashed up. When they're replacing Anteras, BSTs make a big bike feel like a middle weight, so I would think they would turn a V-due into a thing of scalpel-like precision.

Go on - you know you want to!

I really like the MFR wheels, but they don't make them for the Vdue

That is the problem I found with a few dealers . Think I contacted HPS over BST's and they said they had bodged together fitment for a few vdue's but were not doing it anymore as BST did not approve of it . Having dealt with Dymag before I knew they listed most Bimota fitments so went for them on mine.
When I changed the Antera's off the vdue for the first few miles I was getting the apex completely wrong, kept turning to early. Amazing what a change in wheel can do.
I have a bit of experiance with carbon wheels on various bikes , and yes they can feel flighty , but depends on what you like.

So I've ordered the new BST wheels for my V Due Smile literally cannot wait. I'm interested if anybody recommends the 5 over the 5.5 rear wheel as they offer it? Also what are people's views on different tyres. I only ride in the dry so, I'd like something quite slick but both light an grippy are a must.

Agreed. I like the Supercorsas. I use them on my race VFR400 in the SC1 and SC2 compounds. They have a nice profile, wear very well and last a long time. I've got a couple of seasons out of a set including a couple of One Hour races and track days. They still look and feel fine.

I'd get the street compound for road riding as they are made to work at lower temperatures.
