Weld in kit for your 17-20 CRF450R, to convert your frame to accept a 89-2001 Honda CR500 Engine.
The 17-20 CRF450R frame requires some welding modifications to make this engine work properly and make clearance for your exhaust in the center of the frame. *** We recommend you have a professional Tig welder do the fabrication and welding.
WHAT YOU GET:
- Weld on Billet Y Frame section (raw aluminum finish)
-Bolt on Billet front motor mounts
-Weld on lower mounts
-Bolt on Fabricated head stay (bare finish)
-Billet swingarm pivot spacers
Also included is our Ignition Coil Mount that will locate it correctly on the chassis.
OPTIONS / UPGRADES:
You can also choose to purchase our Fuel pump flange *** or make your own.
You can also choose to include Engine Mounting hardware for all motor mounts + head stay *** or use your own.
** If you want to run the older style 85+ (short rod engine) - we recommend running a cylinder spacer and updated long rod crank to get your head stay in the correct location. (Same as newer Cr500) OR if not, you can modify our head stay to work with the short rod... but we will not be making custom ones at this time for the older power plants.
Please allow 1 week production time
