All good ideas come from making problems go away.
Spears Racing has been on the cutting edge of making new products for the little commuter style bikes for decades, most of these products come from the motorcycle being used for something other than what it was intended to be use for…RACING!!
It has been brought to our attention that so many racers have been having shifting issues with the new Kawasaki Ninja 400cc,we have heard everything from “it will not shift” to “it misses shifts” and several of the racers have had to park their motorcycle or just go home.
Look at the the pictures of the engagement area of the shift star and the shift arm on the OEM install, under hard shifting/racing conditions the shift arm will just slip over the end of the shift star and it will leave you missing shifts or leave you to no shifting.
Spears racing has the newest and the latest greatest product this is called the Shift Arm Assist Kit,this kit will allow the shift arm to move closer to the middle of the shift star(See pic)
From the Factory in Chakan, Maharashtra India this bike works well for the commuter or for the daily ride when the bike is taken to the highest level it will have issues.
The problem is solved by installing the new Spears Racing Shift Arm Assist Kit, this will require that the clutch side cover to be removed, the complete clutch assembly and once there it will take approx 15 minutes to make this shifting issue go away.
The kit will consist of the following:
Carbon spring steel snap ring x 1
Machined Stainless Steel Shim Washers x 2 (two different sizes)
