Starting off with a throttle body/manifold kit and a tune is the best bang for your buck you can do for your 2019 and newer Honda CRF110F. This 24mm kit works great with the stock 110cc and has been tested with excellent results on our 132cc kit. All throttle body kits will require a re-map of the stock ECU or aftermarket ECU to increase the amount of fuel delivered to the engine. Running these throttle body kits without a fuel controller will cause the bike to run dangerously lean. Currently we do not offer any flash service but this is something that we are working to offer soon!! Meanwhile, CJR can get your stock ECU flashed with the appropriate tune.


Keihin 24mm or 26mm Throttle Body Kit:
The factory throttle body is a big limitation for the CRF110F coming in at 19mm. Our 24mm kit offers improved performance especially noticeable in the mid range and top end. With a 25% larger butterfly in the throttle body to work with the larger intake manifold. From idle to 5,000rpm the bike feels exactly as it did before (with intake/exhaust/tune), from 5,000rpm and up, the bike does not stop pulling! As you can see from the dyno graph, we are making peak power at the stock 9800rpm limit! Looking at the data behind the scenes, we are able to accelerate 2 full seconds faster on a 3rd gear 15mph to 37mph run. This is a modification you can definitely feel for a night and day different bike.

CJR Performance High Flow CAST Intake Manifold:
This is the largest restriction found on the CRF110. Using the unrestricted intake manifold, it removes the bottleneck restriction found in the stock intake manifold. The stock manifold starts at over 24mm, works down to 13mm in the middle and back to 20mm where it meets the cylinder head. This reduces air flow and decreases performance. The same thing Honda did in 2013-2018 with a smaller 13mm throttle body.

Raw Speed and Design High Flow CNC Intake Manifold:

- Built from 6061-T6 aircraft grade aluminum
- Works with stock or 24mm Honda Grom throttle body
- New hardware is provided to allow interchanging of throttle bodies
- Inner diameter starts with 24.5mm at the throttle body and tapers down to 21.5mm to match the stock cylinder head port
-  Works with the stock injector, map sensor, and hardware

2021 CRF110 24mm+CNC manifold

Currently running a rocket exhuast, aRacer RC mini 5 ECU, 24mm TB and manifold, on straight t4 with the stock intake with the pax racing intake and TB parts cam in the mail as I'm writing this. With the mods I have currently installed the bike doesn't not even feel like the same bike, it doesn't pull so hard the wheel lifts up but I plan to add a high compression piston to give it more snap there. What you get is a bike that pulls for what feels like twice as long as the stock motor, 4th gear is useable and doesn't feel like its falling flat on its face every time you hit the gas in 4th. Every time I get on the bike now I'm surprised by how fast a 110 can go, feels more like a 150r than a 110f.
