Speed Parts from BCD
Joachims Crank is 1 kg lighter than stock
it is cross bored for better durability with revs
at more than 8000 1/min
nice? not really good looking, but this little one is much better balanced than her poor sisters from Berlin
Piston from old Racer with more than 50 hours of hard work done.
and its counterpart the cylinderhead with valves at 46mm/40mm, the 7 mm stems filled with sodium, both in beryllium seats.
Rocker arms on a steel base, with axial ball bearing
micro blasted with nice hexagon socket set screws
external oilfilter with thermostat
second spark plug for real enduros
look from the other side.
