Wheels

[Anders-MZ]

I think switching to 18"21" will be a waste of time and money.

I don't agree on this, I have the offroad-baggi with 18"/21" wheels, it was a BIG difference just change from the original "no-good-for anything" tyres to Metzelers karoo.
I have tried a Baggi SM and the differens is so great that I will buy a set of SM wheels after the winter. It will cost me aprox 1250 euro ($1700) but it's worth every cent. It will take about 15-20 min to change wheels, and that is not a waste of time
If I could afford it, I would have two baggis

Thats a lot of money for a pair of wheels. I traded a used Penske shock for a 18 and 21 complete with tires and discs in like new condition. I'm working on getting a 17 inch setup too. I bought a rear mag off a Skorpion for $100 and adapted it to the baghira. To adapt the front wheel off the skorpion would be much more difficult, unless I changed the brake caliper too. Theoretically, I should be able to order the parts from MZ for the Mastiff that came stock with skorpion wheels, it should be a bolt up installation. However the ability to quick change back to the 18 21 setup is lost when I have to change calipers, brake lines, bleed brakes, etc. The other option is to get a XT600 front wheel (I bought one off ebay for $10) and lace a 17" rim to it, this could be done cheap, but I would like to get away from spoke wheels and tube tires all together. Maybe I can find a mag wheel I can make fit with the stock grimeca caliper.......
You realize you will need a new kickstand with the 17" wheels? Gearing is another issue, you might have to lenghten/shorten chain each time you change wheels.

just keep a complete front brake system with master, line, and caliper, then changing only takes 10 minutes!

...... I bought a rear mag off a Skorpion for $100 and adapted it to the baghira......

What adaptation was needed to stick the Skorpion mag wheel to the Baggi? I am looking for another rear wheel so that I will be able to fit a hard touring tyre on one for when I am commuting, but have a soft compound tyre on the other for when hooning about with others. Much quicker and simpler that having to remove the wheel, take it to the dealer, get him to change tyres, then travel home and refit the wheel.

Need to do this soon, as lots of events planned for 2005 (including a 3 day ride out in France). Roll on 2005.

I had to fabricate three spacers, and bore the hub bearing journals 2mm larger (delicate job) to accept the larger 6004 bearings. The Baghira has a larger diameter axle than the skorpion so I had to go with larger bearings. You have to have an accurate milling machine with a boring head and a lathe and a considerable amount of time set aside. If anyone is really serious about doing it, I could supply some digital photos and measurements. I've put 4000 miles on it, it works. I don't have to replace spokes anymore. However the mag weighs much more than the spoke wheel.

Phlat, Yeah, that would be the hot set up, change the brakes from the lever down and not have to bleed them.

Excuse my ignorance on this, but I thought the Baghira and the Mastiff had the same front brake/wheel setup. Obvoiusly this is not the case. What are the differences.

There was a time when the Mastiff was available with mag wheels that looked like Skorpion wheels. My parts manual shows the part numbers for the mag wheels for the Mastiff. I emailed the owner of the bike in this picture a while back and he said the caliper was a Brembo. Does anyone got one of these bikes? I sure would like to see some close up photos of the front wheel.

Hi

I have today recieved my copy of the MZ parts manual and can give the following info which may be of help.

Wire wheels
Front bearings DIN 625-6003 2RS(17mm ID) rear bearings DIN 625-6204 2RS (20mmID)

Alloy wheels
Front bearings DIN 625 6004 (20mmID) 2RS Rear bearings DIN 625 -6203(correction sorry) 2RS (20mmID)

The same axle is used for all bikes, but with sleeves to make up the difference between them.

This would explain why Demark bored out eh standard bearings to fit standard axles. I think.

The front and rear brake calipers and there mounting brackets specified for the alloy wheeled bike are diffrent to the wire wheeled bike.

That manual is going to be like gold dust

[DEmark]

Thanks for the info, I find that manual a little hard to use. One correction, I bored the wheel itself 2mm larger to accept the larger bearing. The bearings out of the skorpion wheel had too small an ID, the bearing with the proper ID did not have the proper OD but was 2 mm larger, so, I had to bore the recess where the bearing sets, in the wheel itself 2 mm larger, and maintain the proper interference fit, mess it up, and you need a new wheel. I was able to use the skorpion sprocket bearings, just remove the bushing sleeve and the baghira axle fits the bearing.

[keithcross]

whoops please see correction on previous post (I have 6304 bearings fixed in my mind, they are common in lots of places on the 1100 goldwing)
Looing at teh parts manual, I would have been tempteed to order the corrrect axle for the alloy wheel (17mm diameter) and made (or had made) different spacers to take the spindle. As the swinging arm is the same there is less risk of messing things up.

$1,700.00!!!!!!!! You could buy a used dirt bike for that and have a bike to thrash around off road and not risk breaking your street ride.

It's the other way around, $1,700 is for a set of brand new MZ original SM wheels (including tyres) for my Baggi to get a nice street bike.
I allready have the 21"/18" off-road wheels.
I know it sounds expensive but Sweden is a expensive place to live in. The sales tax, VAT, is 25% and the USD dropped 30-35% a couple month ago. Six month ago the wheels would cost $875 plus VAT.

A low budget solution is to use three spoked mag wheels from a Kawasaki ZX6R 95-97. Then I have to make a new front axel and spacers to get the brake calipers in position. Maybe I will go for this solution, I don't know yet, I think the Original looks much better.

[smr96]

Ok, 1700 isn't that bad. Here most getting into supermoto pay 1200 to 1500 to put 17's on their dirt bikes and then another 200 to 300 for tires. I too would opt for getting the factory original rims. Sometimes its better to pay more to be sure it's going to work properly.

Hello DEmark

I have a mastiff with the mag wheels.
Here are a few photos of the bike and the front wheel with the Brembo.
