Harris Magnum 1

[Pigford]

Had an email back from Oliver at Harris Performance.........

Hi Mark,

The Magnum 1 and 2 are virtually identical but your frame is the Magnum 1.

I have sent you an appropriate dating letter.

I see a single sided arm has been fitted. Looking at your shock position and angle you may have difficulties finding a shock spring firm enough to make it work. It will need to be approximately double the stiffness of the original Mag 2 spring. I would estimate at least a 150Nmm spring would be needed, maybe more.
A rough method for calculating required spring weight is to measure the shock length when the wheel is on the ground, then measure the shock length when the wheel is at full bump. This gives the shock stroke. The required spring rate in N/mm is approximately 5000/stroke.

YeeHaa - they arrived today








Just awaiting my new swingarm (not the standard Harris item)....

You'd better put some serious ponies in the engine to push those around

Ignore him Rich he's just showing off.

As luck would have it, the front wheel came with the axel - and it fits straight on my ZZR1100 forks Just need to make an extra 12mm spacer as I won't be using the speedo drive.

Unfortunately (and you probably won't believe me) one of the disc carriers has taken a "whack" and the disc has a 5mm run-out now SO I may just have to have 1 x disc up front

You love single discs. Would love to build one of these, you beat me to it. Love the wheels.

Must admit a Harris/Rickman/Spondon/Martin, etc has been on my "Want List" for many years.......... and as this was only down the road from me (& you ) it was too good to turn down
