    Over the years I have had many speciality springs made and latterly for http://www.ramshox.com. – site is being replaced – but it will give you an idea.

    I will be needing upgraded items for my Glemseck project.

    Many of you will know that Redditch is the spring capital of the UK – remember “Terry’s Springs” ? You will if you’ve rebuilt many Brit bikes – best valve springs available – allegedly.

    My tame spring man will make me just one set if I ask nicely, but as with the other springs now available from Realm Engineering, makes sense to have a batch made. Gets the cost down and everyone benefits from a bespoke product at an off the shelf price.

    So, any interest ?

    Particularly those peeps with the dreaded “air assist” front forks !

    I did a replacement progressive fork spring for my Vindicator Cafe Racer [ Yamaha TR1 based }and it transformed the handling – not to mention a simplified set up and maintenance.

    So here’s what I plan to investigate

    Progressive fork springs
    Uprated clutch springs – say 25%- 30%

    Anyone interested ?


    I am definitely interested in the progressive fork springs but I would need an indication on price before I commit.


    KK – as ever, depends on quantities.

    I developed the K100 springs shown and initially I had to commit to 20 springs [ 10 bikes ].

    However, when the sales started to grow I could order in greater quantities [ 100 springs ], bringing the price down considerably to sub £75 / pair retail.

    However, they were developed over 5 years ago, I will call in on my tame spring man as soon as I have a sample clutch spring to show him. I already have a stock KZ spring from my bike.

    For the air assist spring replacements I will need some sort of spec / sample.

    Incidentally, these springs are made from the same Swedish spring steel that top aftermarket spring manufacturers use.

    I need to go ahead with the clutch springs anyway, but of course it doesn’t make sense to have just 1 or 2 sets made !


    I just paid a visit to my tame spring man.

    Absolutely NO problem. He has ample stocks of the correct grade high quality spring wire to make both clutch and fork springs.

    I WILL go ahead with the clutch springs anyway. I need to order 100 springs minimum, which is only 20 bike’s worth ! Just as a matter of interest I’ll check the price availability of OEM clutch springs.

    The fork springs are another matter, as the unit cost is significantly higher – not huge, but I have to be certain there is interest before I commit to placing an order. However, I expect a unit cost of less than £75 / pair with an initial order of 50 springs.

    Like I said – any interest ??


    To date I have the following info. on OEM and uprated [ Barnett ] clutch springs.

    I’ve found new OEM springs at £7.00 each + p&p.

    Barnett uprated [ 10 – 15% ] £43.50 [ from the USA ] but that doesn’t include any customs duty or VAT. That’s for a set [ 5 ].

    I’m looking at 20% minimum uprated.

    In minimum quantity it looks like around £5.00 per spring [ 20% uprated ].
