Big Bore Kit - Kitaco 160cc SE-4V / KLX/DRZ110 *

Complete 160cc 4-Valve Big Bore Kit. Kitaco engineers designed a brand new SOHC 4-Valve head that produces exceptional horsepower and is available in two displacement packages. This 160cc version and a very potent 143cc version. Key features of this new head design include: centered spark plug location for superior combustion effeciency, Pent Roof combustion chamber design and the use of Y-Style slipper type rocker arms. This rocker arm design is lighter weight then typical screw type and runs with less friction. A forged, 60mm piston with MoS2 coating is matched to an aluminum cylinder with a plated aluminum sleeve. A 56mm stroker crankshaft is then used to create a displacement of 160cc. This is the same engine kit used by the BBR Race Team to dominate the MM12E class in 2008.

  • Aluminum cylinder with plated aluminum sleeve
  • Forged, moly coated piston kit (60mm/14mm pin)
