For Higher than 300-1
gear ratio's, then you
should consider this
series of Double Worm
units each CHM
series
worm unit is
dimenstional the same
as the Motovario NMRV
Series and by using an
additional bolt on kit
it is possible to join the
two worm units together
to provide a mulitude of
gearing ratios and mounting positions? The series is almost dimensional identical to Motovario own Double worm series NMRV/NMRV with only slight dimentional differences in the Adaptor Kit that couples the two units together!
