This Carbon fibre chassis kit is like no other conversion kit available today, It includes alloy rear swingarm with carbon fibre arms. The drive gearing for the KB-4 is chain drive using the stock HOR chain compared to the belt driven KB3.
 
Like the previous KB3 the KB4 Chassis has a number of tuning features and ZH-Racing offer a full range of parts and options to suit any setup requirements and user preferences. 
 
Transform your Kyosho HOR into a modern day race bike, with scale looks and realism like no other RC Bike available. The KB4 Chassis has adjustment options for head angle, shock position, weight and COG adjustments, along with variable swingarm length, the KB4 chassis will also accomodate a servo and cable routing to run an independant front brake on the bike.
