BMW Fork Conversion Kits – 7 Series

$1,080.00 AUD

Our long awaited newly updated BMW fork conversion kits!

You asked, and we listened. Now available in two different offsets (30mm and 40mm), and available for all major forks ranging from Honda CBR, Yamaha R1, Suzuki GSXR and more.

A custom designed plug and play installation to remove those old K series forks and replacing them with modern upside down forks for your custom BMW K series motorcycle. This easy to install modification will instantly change the performance, look and feel of your custom BMW K100, K75, K1100 Cafe Racer, Scrambler, Tracker and so on.

These custom triple clamps are manufactured using the highest quality racing grade 7075 T6 Aluminium for extra lateral rigidity resulting in improved handling and performance. With this kit, you don’t only get style and functionality, but performance of the highest degree.

Be sure to select your Bike Model, Fork Model, Fork Diameters (Top fork diameter = 50mm, Bottom fork diameter = 53mm to 56mm), and the offset your require.

50/53mm indicates 50mm top diameter and 53mm bottom diameter, 50/54mm indicates 50mm to diameter and 54mm bottom diameter etc.

The fork offset is responsible for stability and side to side steering lock. Depending on your set-up and style you may choose 30mm (tucked in front, tighter steering angle, closer proximity to tank) or 40mm (increased front, increased steering angle, increased proximity to tank).

Refer to the specifications below for additional information regarding fitment, application and compatibility.

All orders take approximately 10 business days to process.

Pre-pressed head stem and bottom bearing

Whilst we always recommend that our components are installed by a qualified mechanic, all the hard work has already been done. The kit ensures that the head stem and bottom bearing are pressed on, making the installation a breeze.

We’ve also added two helicoiled mounting holes either side, along with adjustable steering stoppers to suit the needs of your build.

They just incredible!

I still didn’t have to to install it, but it was delivered so fast to the US and the quality of parts is just mind blowing. So happy that I decided to place order here. Definitely will come back for more goodies for my k1100rs.
