Has anybody tried swapping wheels between R1200S and HP2 Sport?

Email Kevin (stonej@mweb.co.za). He will give you all the details.

...there is none... other than the different looks...

shreddr, I am ready whenever you get the heads up the wheels are there. For me, I generally call the bank and give them the info, and they handle it.

Si,
the guy i used to talk to was Ron Turner,(who would have thought , two Turners, eh)
I wonder what happened.

Just a thought on the weight of the wheels issue. Is it better to concentrate on reducing the sprung weight rather than the unsprung weight. Which nets the greatest bang for the buck. I see the wheels as spinning masses and the higher the weight out on the rims the more stable it makes the platform. The gyro effect. This is just a thought.

your gonna get a bunch of responses on this one, but the short answer is getting rid of unsprung weight is where its at! and regarding the stability of the higher spinning mass of the heavier wheels, you are right, but that is also the rub. if you want to do an experiment take a bicycle wheel in both hands and have somebody spin it, and then try to tilt it. you will fell the resistance of the gyroscopic force (angular momentum) to doing this. when the wheel weighs more, the force required to tilt (turn) it becomes greater. when you hear the owners of CF wheels talk about the quicker turn in, this is what they are referring too. the other piece of this is that unprung weight is just that, non suspended. imagine if the whole bike was rigid, the ride would suck. then you could put a spring under the saddle (as older models did) and you would be suspending the rider, which would be better, but you would still feel that unspended bike squirming below you. so just keep carrying out the analogy and you will see why the reduction of unsprung weight is truly a great place to save weight.

No, unsprung weight is what upset the chassis and suspension. In an ideal world, unsprung weight would be zero. Further more, every ounce of weight can become kilo's at speed when rotating, which makes it harder to steer, costs more power to accelerate and make the brakes work harder to slow down.

Of course all weight should be as low as possible, but there really are no benefits for unsprung weight. It is just dead weight.

Keep it coming, I'm storing this info on my internal hard drive.

[throttlemeister]

Think of it like this: if unsprung weight would be zero, you would not need dampers, just springs.

...in terms of motorcycles ; that's a cheap performance gain...
...I think...

Im not familiar with the Magtan wheels. Has anyone ordered those ??? Id rather have metal than CF, especially if they actually weigh less ! Also, how do the Scnitzer wheels compare in the price/weight scheme ??

[leafman60]

Aww, shucks, did this thread just die ?? Or, did everyone wreck their bikes with faulty lightweight wheels?

[shreddr]

I'm not sure if the main question ever got answered, but I am loving the BST wheels on my bike, they feel great, and look *****in!! If any HP2S owner wants to see if they fit, I would be up to pulling them off and giving it a try. As long as I get to test ride the HP2S as part of the process!

[Jonas The Swede]

I've managed to find some used R1200ST wheels that I'm planning to use on my HP2S. The idea is to put rain tires on them for "easy to shift" use on my track days.

I'll let you know if my brilliant idea works!

BTW this is how much fun we have on our trackdays in Sweden!

Whats so fun about wearing neon? Friends don't let friends wear neon.

It made me feel "special"...

[leafman60]

So, what ever happened to the Magtans ???? Where do you get em, anyway ??? Anyone know ?

[Jonas The Swede]

Ok, here's the deal!

The back wheel fits right of the R1200S (ST in my case), but the front wheel doesn't fit right away.

The problem is the ABS-sensor ring. It's deeper on the R1200S and touches the ABS sensor on the HP2. If neither of the R1200S nor the HP2S has ABS I guess it fit's right away!

However, as just reported, HP2 Sport fitment may be problematic due to ABS ring problems. Incidentally, this has just come up as a potential issue with BST wheels too.

[2wheelmike]

Is that a set of the Magtans on the R12S in the webike.net link? Those look way better than the BST wheel on the rear as it's a purpose built wheel for single-side swingarm. Is there a U.S. distributor?
