We display live inventory for in-stock items. However, due to the vast catalog of products this brand offers, we can drop ship products directly from Öhlins USA. Additionally, many Öhlins products are set up based on specific rider weight before shipping to ensure optimal performance.
Please note that supply chain-related delays are possible. If the item you ordered is backordered, we will contact you with an updated ETA.

The racing inspired FKR cartridge kit has technology derived straight from the Moto3, Moto 2 and World Superbike championships developed by our engineers in Sweden and is designed for high end racing.
The FKR Cartridge kit features a spring pressurized system, compared to the old gas pressurized system, the spring pressure offers a more simplistic and user friendly design that also accounts for easier maintenance. But there are more advantages of a spring pressurized system. There is no risk of gas leakage, it also gives a more consistent performance curve and allows for a more compact design. With the Öhlins TTX technology, a new designed piston and an 8mm piston shaft we reduce the pressure build-up and create a faster damping response. That gives a “linear” style of damping characteristics which create more tuning options and also increases grip and bump absorption properties while improving chassis stability.
Spring rate selection is based on rider weight. You will find recommendations for this in the mounting instructions (see downloads).
Various special tools and fork oil are required for the correct installation of the cartridge kit (see mounting instructions). These are not included in the scope of delivery and can also be ordered from the Öhlins online shop.
Öhlins DTC does not provide technical support! We therefore strongly recommend having the cartridge kit installed in a specialist workshop. You can find an overview of authorized Öhlins dealers and service centers in our dealer locator.

The higher pressure cap stopped my overflow from becoming pressurized and blowing out. I did a combustion gas test on the cooing system and it passed all 3 times, so it made since the factory cap was to low of a rating for serve duty.
The internet provides many options. Not all are good. HHR provides top notch customer service and the best parts available.
quick shipper
awesome customer service
I ordered Avio fiber glass fairing and all necessary brackets for 2023 Yamaha r1. HHR answered all my questions by email and later by phone. The staff I communicated with were knowledgeable, straightforward, helpful, and non-judgmental. I've had been using the products for more than a year, and I have no complaints and am quite happy with it. I've heard it's easy to installl, too, but I had someone else do it, so I can't say if that's true. The bodywork has cutouts for the tail light and headlights. Works great.
