Brc 510cc Conversion Kit KTM Carb 2017-2018

Description

The BRC 510cc conversion kit is a donor-engine conversion package for 2017-2018 KTM 250 and 300 EXC/XC-W carburetted models, intended to rebuild the original engine into a 510cc configuration. It is designed for strip-down and assembly work using supplied conversion components together with selected parts from the existing engine, rather than as a complete ready-to-run engine.

Important Information

  • This is a conversion kit that uses the engine from the listed application and reuses parts from the original engine to build the 510cc engine.
  • The build reuses the donor engine’s transmission, clutch assembly, kicker assembly, water pump, intake, ignition and covers where possible.
  • Due to the value of the kit, it is shipped on a single small pallet.
  • No warranty is implied or given due to the custom nature of the kit.
  • Check that all supplied and reused parts are correct before beginning assembly.
  • Due to US and EU model differences, modifications may be required to mounts, exhaust or other supporting parts.
  • A signed waiver confirming acceptance of these conditions is required before dispatch.

Features

  • Pneumatic power valve system
  • Linear, smooth power delivery
  • Accepts the donor 5-speed or 6-speed transmission
  • Compatible with kick start and electric start arrangements
  • Decompression button fitted to assist starting
  • Integral counterbalance shaft
  • Intended to run with the stock donor carburettor on carburetted applications
