This motor mount bolts the Yamaha KT100 engine to your kart frame and adds a third bearing that supports the crankshaft. It cuts flex and vibration so power stays consistent through the race instead of fading when the engine twists under load.

New to karting? This bracket is what holds the engine firmly to the chassis. The extra bearing keeps the crank from moving around so the engine runs smoother and needs less fiddling between heats.

Seven variants let you match your exact chassis rails without extra parts. The no-clamp version works for custom setups while the integrated clamp models fit common 28-32 mm rails in either 90 or 92 mm widths. Every kit ships complete with the bolts and washers shown.
