Harris rear spring

[Mole28]

Can anyone tell me the spring rate for the rear shock on a Harris Magnum 2? It has a proper monoshock as opposed to a rising rate setup so presumably the spring rate will be a lot stiffer. We took our endurance bike out for its first run today and apart from some teething problems  it was lovely albeit  a bit wallowy.

I saw that this had been moved to trick frames. I re-posted it in members projects for a wider audience. My bad as the kids say.

Give Harris a bell in the morning. They should be able to tell you straight away.

Good to meet you today @Mole28.

The bike looks and sounds stunning.

Not sure how close your set up is to the original Harris swing arm. 

You'll need to know the motion ratio of the rear suspension. Wheel travel v shock travel. A small difference here can have quite an effect in spring rate.

once you know that give  Harris or  Maxton a call, they'll be able to advise

Yeah, good to meet you too. I'll get everything measured up and make some calls. I was just looking for a ballpark rate for the spring as ours is definitely undersprung.

Bike looks great,  is that a b12 adapted swinging arm ? More pics please. Don't know the standard spring rate but this is the EMC shock that came with my mag 2.

have a chat with John Neate or his sons -  ok not everyone is in support of their choice of engine but they do know a thing or two about setting up these frames / suspension

Last year they made an improvement by fitting a longer swing arm - hence a chat
