These are expansion chambers for the Kawasaki KH500/Mach III two stroke triple made by K2tec, a new Japanese outfit aimed at two stroke enthusiasts.

For the nostalgics here's one of their many offerings for the RD/RZ250:

Given welding quality I was pretty surprised at the price: the RD exhaust system you see above is less than €580, but they have cheaper (albeit less performing) systems available which, according to them, do not require re-jetting.

It's good to see there are still people out there throwing money and sweat at two stroke engines which aren't the usual Chinese junk. Thumbs Up

Do look good quality for the price.

Often wondered, as while I know Honda & probably the other Jap bike makes quality may have slipped a bit in the last 10-15 years, do the Japanese actually make anything on par with China in terms of close to junk?

Since this is Japan can we miss the highly modified scooters? Laugh

There's a whole subculture in Japan aimed at highly beefing up scooters. I am not talking about just slapping on a very loud exhaust to annoy passerbys but seriously expensive stuff, such as frame modifications.

Those above are used in acceleration races, which for scooters are usually held on 1/32th of a mile, allowing them to be held in abandoned industrial parks and the like. A great way to spend an afternoon... and ungodly amounts of money! Laugh

Was looking at that one myself, looks like that hydraulic ram pushes the rear underneath cos at present the exhaust is facing the wrong way then makes the bike higher and shorter Yes

The engines used in scooter drag racing are very small by Western standards: most use as starting point a 50cc two stroke engine which isn't exactly a large engine to start with.
For reference the engine used in this contraption comes from a Yamaha Jog-Z and has been modified (among many other things) with a big bore top end bringing its displacement to 100cc:

My cousins the other side of the Alps have copied the format but struggle to understand the concept that a drag racer is supposed to carry as little weight as possible, not huge air filters out of a Rolls-Royce Merlin. Laugh
