complete Stage 6 "mk1" 70cc cylinder kit for HONDA HOBBIT!!! that's right, 20+ hp out of the box with bolt on stage 6 components...high 20's with proper tuning, port adjusting and guru mastery. get ready to break ummm the speed of light barrier. and a lot of other things.

custom designed base plate allows the stage 6 cylinder to bolt directly to hobbit cases, with no case matching necessary at all. that's right, it all flows perfectly right into the stock (but massive) honda hobbit side and top transfer ports. a second, aluminum spigot for the cylinder is included (the original application has the water flow from the head through the cylinder then through the bottom of the case and out). last but not least a 12mm super stuffy crank is included to allow ya to uh...be able to do the whole thing ya know. so ya get the kit, the crank, the adapter plate, and the additional inlet / outlet spigot. DOES NOT INCLUDE anything else!

the cases WILL NEED TO BE OPENED UP!! that's right, the sleeve is big (58mm OD), so you need to mill or drum sand the crankcase opening out to fit. very easy though as the skirt does not protrude very far into the case. like half the work of doing e50 cases for a gila. also, you will need to open up hobbit base gaskets with a modeling knife to get them to work with the larger skirt...no biggie. also on that note, to achieve your desired final squish you will need to use hobbit base gaskets. the spacer is currently set up to have a squish of 0.80mm while using all of the stage 6 o-rings and one oem hobbit base gasket.

also remember, this will require custom fabrication for exhausts (though the minarelli horizontal stage 6 exhaust apparently almost bolt up perfectly!) and other custom fab. this is a pro series kit...serious gurus ONLY. seriously!! i built one and am too scared to run it!!

The special adapter plate bolts to the engine case, the cylinder is mounted via external bolts so that there are no bolts cutting through the cylinder; this new design opens up all kinds of options for tuners to modify and optimize their engine (porting) without being subject to the usual restrictions. A Viton O-ring seal between adapter plate and cylinder makes future readjustments unnecessary.

Regarding performance, the Stage6 R/T 70cc Cylinder Kit MKI Piaggio NRG / Runner reaches 20 to 22hp and can easily be placed among the top 70cc high-end racing kits on the market. The thermal properties are excellent - the combustion chamber is bolted to the cylinder at five points, each coming with its own cooling pocket. These highly critical areas are thus stabilized and the risk of piston seizure is minimized.

The exhaust flange is attached with 3 bolts. It is suitable for Stage6 R/T exhausts, other flange types are available.
