MotorSport Wheels vs. Regular Wheels?

I know the MotorSport Wheels are lighter than the regular Wheels but does anyone know the specific delta in weight?

I do my tire changes and I gotta say the regular rear Wheel is very light...is the MotorSport rear wheel a whole lot lighter?

As for the front wheel, I can only guess it's very light as well but the OEM Discs make it feel heavy.

With all that said, would lighter Discs result in a larger delta in weight versus swapping in MotorSport Wheels with OEM Discs?

Re: MotorSport Wheels vs. Regular Wheels?

From Max BMW parts. And sure lighter rotors will make a difference as well.

FOR VEHICLES WITH SPECIAL MODEL (CODE: X393A) :
01 71 60 7 710 904 HP FORGED WHEEL, FRONT - 3,5X17 9.30 1 $1,530.00ADD TO CART

Part Thumbnail
• HP Forged wheels for the newest K bikes.
• Material - Made of aluminum alloy that ensures optimal strength of the wheels.
• Color - Magnesium metallic matt, triple-coat paint finish.
• Front wheel includes wheel bearing, sealing ring and tubular spacer.
Weight savings of approximately 2.4 lbs per set by comparison with the standard wheels.
• Maximum payload is unchanged - despite the lightweight construction, the motorcycle still retains its full carrying capability for 2-up riding and with luggage.
• Dynamic “Y” design of the spokes adds emphasis to the sporty look of the bike.
• These wheels can be used in combination with RDC and ASC. - Installation by an authorized BMW Motorrad dealer is recommended.
• Brake discs are not included.
• Front: 3.5 x 17” - 120/70 - ZR17
• Rear : 6 x 17” - 190/50 - ZR17

Note for models with ASC:
The sizes of the front and rear wheels of a motorcycle are programmed into the model-specific characteristic maps of the control units. If installing HP forged wheels involves a change in wheel size, the data release must be updated accordingly: on CIP CD 10.0 and later there is a dedicated data release for this purpose, which has to be coded to allow for the switch to HP wheels - See service bulletin #36 001 07 (038)

Re: MotorSport Wheels vs. Regular Wheels?

For all the talk of "I need more power" people need to remember that the motorcycle lap record at the Nurburgring was set by a Yamaha R1 with a standard engine, but with Carbon Fibre wheels fitted and the suspension tuned to suit, proving that it's all about corner speed, not how fast you can go in a straight line.

The forged HP wheels on the S1000R are supposed to be approx 2kg lighter than the stock aluminium wheel set, according to BMW.

Re: MotorSport Wheels vs. Regular Wheels?

Thanks for the responses...but...ahhh...we have a difference of weight saved data.

So is it 2.4 Lbs (1.09 kg)?

- OR -

Is it 2 kg (4.4 lbs)?

- AND -

Welshman: "not how fast you can go in a straight line." - agree but...

...acceleration rate is improved due to the quicker spin up of the lighter rolling mass. Thus you may get to the next corner sooner.

Both are correct - K1300S wheels are different than the S1000R wheels. The weight savings for the K1300S is 2.4 lbs. and the weight savings for the S1000R is 4.4 lbs.

All this info can be found going to Max's parts page and looking at the forged wheels for the particular bike - it gives this info in the description.

Well spotted. I had forgotten about that. Having had CF wheels put on my S1000XR I can confirm that you could notice the difference!

Carbon rotors are available from Lyndall. My set cost $1,000 and have been trouble free.

And the BSTís are as light again,I canít see the point in the HPís ok if your buying a production bike and they are already on but aftermarket(any) are a league better(lighter) I mean a LEAGUE better after a few weeks of getting to know a bike I did it out of necessity on the K even my wife said ĎDoesnít go where you want it to does ití too effing right was the reply.

Go into the RR forums which where I went when on the trail for some kind of rough guide for X/R wheels weights and you will various weight for all the aftermarket stuff.

If you go BST look at MotoWheels
