Exhaust system for HONDA CR500 ’89-’90 and ’91
From now on in stock exhaust system for HONDA CR500 ’89-’90 and ’91 complete exhaust with silencer from the well-known brand H.G.S. exhaust systems.
Replica Maico ’81 (motor ’83-’84) frame
On behalf of a customer, BZS has adapted a MAICO ’81 frame in such a way that the Maico engine block from ’83 and ’84 (shorter engine) fits in the frame and all parts of the ’81 can be used, except for the exhaust, the geometry is exactly that of the ’81 there, but the bottom frame has been modified so that the shorter block fits perfectly.
This exact replica is by B.Z.S. Racing Parts rebuilt with great precision from high-grade chromium-molybdenum tube (25CrMo4).
The welding takes place TIG with special welding wire.
These frames are thus supplied as a kit:
– Frame incl swing arm
– Axle and swing arm bearings
– Steering bearings
The complete frame including the swing arm weighs 14.4 kg
(Original Maico ’81 15,5 kg)

After discussions with the factory mechanic from MAICO in the years ’78 to ’82, Steve Butler, and factory driver Yvan van de Broeck, we came to this result of the model ’81. This is because in the year ’81 three different frames were built and delivered. This version is the best MAICO ever built according to the ex factory team mechanic and factory rider. At that time he already got the nickname “The best twinshockbike ever build”

MAICO ’81 frame for installation of other engines
At the request of a German customer, we have supplied a Maico frame without motor mounting and a slightly wider swing arm. He will use this frame to build in an engine block of a HONDA CR500. In the UK in particular, many MAICO ’81 frames are used to install four-stroke engines.
The benefits of this frame; has the best steering characteristics of the twin-shock models and a lot of space, so every engine fits into it. All standard Maico plastic can be used.

Because that the brake pedal of an XR500 is very difficult to find. We made our own brake pedal with the original mounting (we can also supply the special bolt). The point of engagement for the cable is higher and there is just enough room to pivot the kickstarter.
