Horex produced bikes in Germany between 1920
& 1960. The name was revived in 2010 and the VR6 was designed. The
company went bust in 2014 but were bought last year by the 3C-Carbon Composite
Company who intent to market the VR6.
The bike is a sort of naked retro
but with an interesting engine. It is a 1200cc 6 cylinder in a VR
configuration. That is half-way between an inline engine and a vee (the R is
from "Reihenmotor" = inline engine) It is a narrow angle vee engine
with staggered cylinders and a single cylinder head. There are three valves
per cylinder and three overhead camshafts. The engine is claimed to produce 170
bhp.
Volkswagen use a VR6 engine in many of their cars.
