\/><\/a><\/figure>\n<\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>The conversion is very labor-intensive, requiring many new and modified parts. The kit includes the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hybrid swingarm<\/li>\n\n\n\n<li>Lowerrail<\/li>\n\n\n\n<li>Rear frame section Yfz450r<\/li>\n\n\n\n<li>Engine Mounts<\/li>\n\n\n\n<li>Case Bushings<\/li>\n\n\n\n<li>Intake tube<\/li>\n\n\n\n<li>Airbox<\/li>\n\n\n\n<li>Reiger Yfzr\/CRF Rear shockabsorber<\/li>\n\n\n\n<li>Lonestar linkage system<\/li>\n\n\n\n<li>ECU Mounting bracket<\/li>\n<\/ul>\n\n\n\n<p>Due to the position of the throttle body, the entire rear shock absorber needed to be revised. A solution was developed in collaboration with Reigersuspension. A shorter shock absorber with the same stroke offered the solution. This guaranteed the preservation of the beloved geometry of the Yamaha YFZ450R.<\/p>\n\n\n\n<p>Conversion kit prices start from \u20ac5.456,78 excluding TAX.<\/p>\n\n\n\n<p>A fully serviced conversion is available upon request.
