I'm loving little bikes more and more lately and this one is awesome.

the only 2 rear vertical frame tubes are not beefed up unless they replaced them and made them look original :
the loads are extremely different on a single shock frame
basically the shock and swinger pivot are trying to tear the frame apart,right there at the weak point, above the rear motor mounts
totally diffferent than what the frame is designed for
the top shock mount is really adding to the grief as it is hung out rearward compounding the stupid with twisting loads on those 2 tubes
and the entire rear frame is removed
it actually contributed to absorbing laterall loads at the swinger pivot, now with the much longer swinger the loads are even higher with a reduced capacity to deal with them, than even the original had

looks like right side shiftvibration said:This one caught my eye...
Scooter trash said:Doesn't look all that efficient. The fulcrum angle isn't really direct and puts a lot of stress on a small bearing load area. Also it looks like a converted hydraulic piston swash plate pump.
It's efficient in several ways, particularly in their absence of valves, high compression with the same power stroke as a 6 cylinder, and it's low vibration...Scooter trash said:Doesn't look all that efficient.

yup and i think the entire design started with the idear of the way the cylinders have no poppet valves but slide past portsdeviant said:It's efficient in several ways, particularly in their absence of valves, high compression with the same power stroke as a 6 cylinder, and it's low vibration...
