North Pole Motor 2/4

When I rode on the frozen Beaufort Sea I gained a wealth of experiences. Unfortunately, one of them was that even with quite a few adjustments to the Polar Ice-R1 I would not reach the North Pole. Another one had to come.
In order to follow the right path, I first worked out/figured out all possible solutions to the bottlenecks in my head. They are described below.

Swingarm

A custome-made swingarm will be necessary to fit the bigger and wider rear tyre. Because of the larger wheel diameter, it has to be a lot longer than the original one. Also, an extra axle has to be placed in the swingarm. Probably I am going to build one of steel first, because then I can easily adapt it myself. If everything works as it should, the final version needs to be made of aluminium.

Front forks

After extending the front forks by the inventors of the OSCO Chain Oiler, the 2013 Polar Ice Ride R1 was raised by 65 mm. This way the much bigger front wheel could be fitted, which additionally made the ground clearance even bigger. Because I used the standard R1 front forks, the bike’s suspension had a short distance that it could travel. On this rough terrain it’s much better to have a bigger travel and that’s why the North Pole Bike will have different front legs. This could be a set with the correct length from a random existing bike, but there is also a good chance that Hyperpro -which will take the suspension on its behalf anyhow- will completely develop and manufacture these for this challenge.

Having the right suspension brings extra grip and (road) holding. That was the obvious result from using the Hyperpro suspension during my previous winter challenges. Also, this time there will be built a rear shock unit suitable for the bike.

Triple clamps

Because I want to use a front tyre which is approximately 40 cm wide, wider triple clamps will have to be made.
If there is a company out there willing to do this for me, I shall be pleased to hear!

Clip-ons

Sticking out the front forks a little bit above the triple clamps, will create the option to raise the clip-ons, which in return will straighten up my riding position. The biggest advantage from this I get when the terrain does not allow me to keep my feet on the foot pegs. If in such occasion you hang forward, it isn’t easy to balance or to use one or both feet to step. On top of this it is extremely tiring in that position, especially for the arms.
Probably I’m also going to extend the clip-ons a little bit to facilitate the steering control.
A Hyperpro steering damper will also contribute to a better and easier steering control. A proven concept!
