While internals remain almost identical to the FTR unit, the JFR design does away with the integrated engine oil tank to provide a lighter, more compact design. The resulting front face will retro-fit to the popular LD-200 mounting.
The JFR-200 is available in either 5 or 6-speed variants, both with sequential shift and full semi-auto system compatibility. As with the FTR, free or Powerflow differential options are both available.
