The pictures below show the Surbo (in black in grey pipe) fitted in the air filter box cover of the Honda CBR 150R.

Our grey pipe has an outer diameter of 60mm, so if the cover of your air filter box has a height of 80mm, it should be able to fit.

Testimonial from owner Faredarlee

"Got the Surbo installed on my CBR150R FI. Here's my review after approximately a month of use. Louder/ deeper sound during acceleration, and improved acceleration. Better power when going up slope. Fuel mileage improved from 38 km/l to approximately 42 km/l." Below is the original transcript of the testimonial.

One sports 250 cc Kawasaki with Surbo revved to 16000 rpm. A Vespa scooter saved fuel with the Surbo. A gokart, which had a motorcycle engine, also had much increased power with a Surbo, more so than the same Surbo had on the kart owner's car, possibly due to the light weight of the kart. This means that the Surbo could make a big difference to the power of your bike. Due to a smaller throttle opening for the same power, the Surbo could also cut down emissions, especially for older 2-stroke engines.

Examples of compatible motorcycles

The below is based on available photos of the air filter boxes. There must still be a clearance of at least an inch from other parts of the motorbike, for example, the seat. We will keep updating this list. You might help to suggest more motorbikes. There are videos on how to remove the air filter from motorbikes. You might search for bike brand and model and air filter change and look at the videos, and if you see the air filter cover being taken off, you can send the video to us.

For Yamaha motorcycles:

We had previously done a Yamaha R15 that came with a metal pipe connected to the throttle. Yamaha air filters may not have the space inside for a round bore as for the above bikes, but we are able to replace the air filter box with a cone filter as shown below, a pipe for the Surbo, and a step down adaptor to the throttle. Please let us know the outer diameter of your throttle.
