Has anyone successfully fitted a 848 front wheel on a 916-998 series bike and retain the speedo drive? I'm wondering if it is possible to machine the 848 hub to fit the drive ring and retainer. Can it be adapted to fit a different speedo ring and/or drive. Is there enough meat so the bearing could be recessed a little to allow the ring and drive to fit? I have searched for a thread with a positive outcome to my question but can't find one. Yes, I understand it's not an easy thing and yes I know there are wheels of different patters available for the 916 series. Thanks.:think:

The short answer is no. Why not just get a marchesini front wheel that fits the 996? I know, the cost, the cost, but you may find that it is just as expensive to make it work than to just get the right wheel in the first place and be done with it.
You can do like I did just do a front end swap off an 848 and get a digital dash (Translogic) and eliminate that old looking anolog gauge.

The short answer is no. .

Thanks, what's the long answer? Did you try? What physical aspects of the 848 wheel make it impossible to machine and fit the speedo ring and retainer and a different spacer? Thanks in advance.

748-998:
6 hole 10mm offset rotor
speedo drive

848:
5 hole 15mm offset rotor
no speedo drive
different axle
different spacing

If you an find 15mm offset 6 hole rotors (not cheap), 848 axle and machine for the speedo drive, it can be done.

But it might be cheaper easier in the long run to get some OZ Front Wheel and OZ Rear Wheel
The OZ are as light as the 5 spoke magnesum wheels and lighter and stronger than the 848 wheels

Thanks "M" (is it Matt or Martin?) I have those rotors with the 4 pad calipers on my Bostrom 998s, are you saying to fit these 6 hole rotors to the 848 5 hole wheel or are you referring to fitting a 998 wheel on an 848? Is it just the outer lip of the 848 wheel that needs to be machined off to fit the drive or does the bearing need to be recessed do you think? Thanks for your thoughts. Alan.

I keep reading that you would need a different axle for the front wheel swap, but my friend was able to put 1098S wheels on his 996, while retaining the stock axle, he just had to re-drilled the rotors and lose the speedo.

 

[widewalker]

he just had to re-drilled the rotors

He drilled his 6 hole rotors to match the 5 hole wheel? Thanks.

Yup!

don't mind the stickers, they're gone now

 

[widewalker]

Thanks for the info. I dont mind stickers. LOL

If I recall correctly, the center bore of the rotor was a different size than the wheel hub.
So now the rotor is centered on the rotor bolts?
He must have done a great job aligning the new holes.

I've used spacers on rotors that made the rotors no longer centered on the wheel bub. The rotors felt like wave rotors afterword...

And what did he do to the rear wheel? The 1098 has a bigger axle than the 996. Did he machine an adapter to fit the smaller axle and wheel nut?

I was also very surprised and wonder about the rear wheel as well. I'll see if I can talk to him and get more info on how he did it.

So much fun.
I have a "hybrid" setup on my 1997 748/853 (Anatra).
It all started last year when ECS rebuilt and mounted the Ohilns forks from Helmke's race bike on Anatra (it was a 996 or a 748R, I can find out).
At that time we also mounted Brembo 4-Pad calipers.
Since the 748 rotors use a 10mm offset ECS used 5mm spacers when mounting the calipers.

I decided I wanted Brembo T-Drive rotors and was told that I could not get them with a 6-bolt pattern and 10mm offset by a couple of dealers (yea NOW I see them on MotoWheels... Doh!).

So Steve at ECS said we could use 848 wheels so I could get 5-bolt pattern / 15mm offset T-Drive rotors.
The rear wheel is the same for a 748 and 848 so I bought the 848 T-Drive Rotors and a set of OZ Racing Piega for an 848.
I figured we could get rid of the 5mm spacers too.
We could also reuse the front axle though I opted for an exotic one (I think it is 25mm diameter on both but am not 100% on that but the new one I bought was for a 748).

Well ECS and I completely forgot about the analog speedometer pickup. Steve at ECS said he could have his machine shop modify the front wheel to accommodate the pickup. The thing is that the 848 wheel center is wider (amongst other things). For example, when you remove the 748/916 series speedometer pickup for the track you have to replace it with a spacer. With the 848 wheel we did not need a spacer (therefore we would need to machine it down to fit the pickup).

This would all take a lot of time so Steve at ECS suggested we mount a digital bicycle speedometer to use for this season and have the machine work done in the winter. I decided to help by hunting down a speedometer and in my searching I stumbled on one specifically for motorcycles by Koso. It "splices" into the wiring (no little battery inside it) and is back lit illuminated for night.

Sean at ECS fabricated a couple of simple brackets to mount the Koso where I wanted it. I also had go to Pro-Bolt to get one longer fork/axle pinch bolt since the Koso pickup needed mounting point (we used a longer pinch and secured the pickup mount with a nut on the pinch).

In the end, I have decided that the Koso is a permanent addition to Anatra. We also did an 853 big bore on her at the same time so the analog odometer (that no longer works) shows the 748 mileage and the Koso shows the 853 mileage.
I also want to add a +1 to Moto's suggestion on the OZ Racing Piega wheels. I love them!
Here are some pictures... Hope this helps.

This one kind of shows one of the fabricated brackets for the Koso:

1199/848 rear wheel swap?

I've been doing a bit of asking around at local shops and dealers, etc, trying get a solid answer as to weather or not I can swap my 848 rear wheel with an 1199s. Would it be a straight swap or would it need modifying?

Wrong topic you used, there is alot of info on this board about wheel swaps...

Only way to make it a straight swap if you also swap the excentric hub assembly, axle, rotor, calliper carrier etc... (I recently fitted 1098R wheels (same dimensions as 1199) to my 1099sp)
