This adapter bracket allows you to swap a CBR250R or CBR300R engine into your 2014-2020 Honda Grom MSX125 with zero fabrication required to mount the motor.
Designed and manufactured by a championship winning NASCAR engineer, that builds swaps for fun, the single piece brackets are laser cut from cold rolled steel, designed to be as light as possible, while retaining the necessary strength to handle the increased torque of the 300 motor.
Other overly expensive kits use 2 thin pieces brackets that are prone to bending and misalignment under normal use. Their addition of non triangulated \"beauty\" cutouts to their brackets, in an attempt to reduce weight, has further weaken their bracket\'s ability to withstand the weight and vibration of normal use.
The spacers are cut from 6061 aluminum rod, to the proper size of both the motor and the frame, and comes with grade 8 hardware and nylock nuts.
This is the only kit on the market that comes with a delrin covered chain roller. The proprietary design allows the cover to form to the shape of your chain, and after that break in period, wear becomes non-existent. This also reduces the ear piercing grinding sounds experienced with other kits.
This kit works with all the supporting parts available, and slso works with CB300F, CRF250L, CRF300L, Rebel 300, and CB300R engines.
