Air Filter and Base Assembly. 1979-'80 CR125

Regular price $305.00

The length and shape of the OEM CR125 "Red Bullet" intake tube is absolutely critical to making them run properly. Honda knew exactly what they were doing when they designed the intake system! So, just removing the old set up and bunging on an air filter was not an option for us!

We have spent a number of year designing and developing a new system to replace the overly complicated OEM set up. It had to fit right, look right and perform as Honda intended!!
The 3D printed rubber inlet manifold, is an exact reproduction of the original Honda Item and the base plate is manufactured from heavy duty, 3D-printed ABS plastic.
Once mounted, the filter base doesn't need to be removed for filter changes. Which with this set up, can be changed in less than 60 seconds, with just a screw driver or 6mm socket.
From the outside they look exactly as per the original set up. The carburettor is supported correctly and the front face of the air box is sealed, just as it should be.
Supplied complete with 2, Twin-Air filters.

Since SpD Factory
Developments began, the Company ethos has remained unchanged – ‘Superb quality and nothing less’. Every item that we manufacture or product that we market from other manufacturers must answer one simple question – “Would we be proud to put that on our own bike?”. If the answer is no then we don’t sell it.



In a word, superb! With attention to detail even on a plain old bolt! Very happy with results and well worth the wait.
