Weight Watches for the MZ 125

The article I posted to this blog on the MZ 125 The petite MZ... recieved a comment yesterday. I thought it deserved a posting of it's own.

Pam F from Powroll was searching the net for MZ Scropion info and came across my blog. Here is was left as a comment on the MZ 125....

I was reading your blog after searching MZ Scorpion, and noticed this entry about the MZ125.

Our company did a project with MZ back when these bikes were first being introduced to the US market.

We did tons of testing and created some kits for them - however, MZ was sold before the project was completed. Here's some of what we found out about the little bikes.

1. We're not sure what dyno they used to get that 15 crank hp number, but the real numbers at the rear wheel were way less than 10 hp.

2. A standard Honda SL125 will outrun an MZ125 by at least 5 bike lengths in 1/2 mile.

3. The engine is hugely overbuilt, leaving so much space that we were able to create a 220cc bore kit without sacrificing reliability.

4. The bike weighs alot.

5. There is no way in the world that a stock model could reach 65mph. With a lightweight rider, fully tucked, we achieved 59 mph. Though, on the dyno, the bike will show 65mph without wind resistance.

6. The FunX (with it's streetbike chassis and uber-tall suspension) was the most ill-handling dirt bike I've ever ridden.

7. The MZ 125cc water cooled engine had tons of potential - this could have easily been made into a very fast 250, with bullet-proof reliability, right from the factory.

Tuning 40mm BING CV carburetors for BMW motorcycles by ear.

Steve Doyle has put together this great and simple guide to tuning your Bing carbs. No need for expensive tuning equipment. So over to Steve...... Any feed back on this How To please email me and I will pass it onto Steve.

There are 3 common methods to syncing the carbs. They will all work
1. Shorting the plugs. and
2. Using a manometer of some sort. Carbtune, Twinmax or home made
3. Using your ears. No comprehensive articles that I could find..

In the spirit of learning to service and tune at home and after lots of reading, I decided that for me the "by ear" technique might be the most useful, as it doesn't require any special tools and can be performed anywhere. There is no risk of electrical damage to the bike or the one doing the adjusting.

It was very difficult to find a comprehensive description of the procedure, so using the combined kn…

Ride impression of the Yamaha MT-03.....

Yamaha have realeased their new 660 based single. The MT-03. See I so want one....MT-03 The bike can be had in Europe but not here in Aussie land. I have asked Yamaha Australia if they will bring them in. They said "No plans at this stage to introduce the MT03 in to Australia." To rub salt into the wounds, axxess, the forum admin guy at got to ride one. NOOOO!!! So unfair. He translated his ride impression into English for those of us who will not get to ride this. Thank you mate for doing this for us. So lets see what he has to say.....

Saturday 16 February I could try the Yamaha MT-03 at Gebben Motors. I could try a brand new red 2008 model. After a short instruction and a warning because of the new tires we were ready to go! The first thing I noticed was the enormous wide steer and the upright riding position It gave me a feeling of absolute control and power! The seat was quit hard but not uncomfortable at all.

Unless it was still freezing t…

The petite MZ...

I asked a question on the MZOG • MZ Owners Group if I should call my bike an MZ or a MuZ. I got some very informative replies. One reply was emailed to me with a link to Wikipedia MZ entry.

What really caught my eye on this webpage was this very petite MZ 125 4 stroke water cooled single.

This is what was said about this bike… “MZ currently manufactures a line of 125cc 4-stroke motorcycles using a new and powerful engine designed in-house. The current MZ 125 produces 15 crank-horsepower (11 kW) and almost 10 lbf·ft (14 N·m) of torque. It is a liquid-cooled pressure-lubricated dual-overhead-cam design with 4 valves, high-voltage electronic ignition and an 11000 rpm ignition cut-off. This is officially the most powerful 125cc 4-stroke engine mass-manufactured and has also proved highly reliable. This engine is used in 4 models of motorcycle, all of which share a common frame. The frame is a tube-steel backbone with the engine as a stressed bottom member. Changes in the suspension, facia, …
