  • Lightweight design is much more cost-effective than a traditional steel-sleeved cylinder
  • Can be re-plated repeatedly without boring or re-sleeving

Kit Includes:

  • BPRATV 102mm +2mm Big Bore Cylinder with Nickel / Carbide (Nikasil Plated) Plating
  • Wiseco 102mm 11:1 forged piston kit (includes piston rings, wristpin, and circlips)
