Modern Axle Blocks for the k5

<< < (3/3)

ktmdude:
HC#42, I had the back wheel off last night and pulled a few measurements, no calipers just a metric ruler. 51mm over all, 11mm on the short side to the edge of the hole, 20mm axle hole, and 20mm on the long side to the edge of hole. I am fairly confident in my measurements, I took my time and did my best with what I had. I hope this helps and good luck.

P.s. let me know if you want the height, I would imagine that would be different. (k5 specific)

Hillclimb#42:
Thanks KTM Dude. Overall should equal both sides added together for the reference. Measuring out of center is the ticket. Thanks alot for your help.

ktmdude:
Glad to help. Let me know if you have any luck making some. I would be interested in some cool looking green ones for my 01 250. If you are interested in building them and I would not have to cut off an arm for payment, I can get you the height measurement, and axle diameter.

I run 14/45 on my bike at the dunes. I can launch in second and pull fourth gear up the steepest dune on the pipe so the bikes fun for drag racing and that leaves fifth gear for running flat out down the back side of the dunes wich Is is just a tich over a 100 mph. I'm now makeing a touch more HP then when I went through my gear testing phase so I'v been wanting to try 15/47 on my bike to see if it will pull it like I hope. If I pull fourth on the pipe up a steep dune with 15/47 on my bike that will make me most happy  :-D I would not recommend this ratio for a stock bike, Your s**t better be running good to pull this ratio hard in fourth Up a big sand dune with a paddle tire.
