TEC front fork progressive spring upgrade

Hi everyone - have recently had OEC front fork springs (linear) replaced with TEC progressive springs. Report : definite and substantial improvement, virtually no dive on firm/hard breaking, probably smoother ride over uneven surfaces. Impression - definitely worthwhile.

Perfect timing, Greybeard! I just ordered the TEC progressive springs and pre-load adjusters last night. Did you mess around with the fork oil at all or just pull the OEM springs and drop the new ones in?

Each one matters.

Hi! No pre-load adjusters fitted as wished to reduce cost. No fork oil change required either. I am impressed with lack of forward diving on hard front breaking.

Good to hear. I was hoping for an easy install. I was contemplating a new rear shock, but the dive when braking bothers me a lot more than the bumps on the road at this point. Great news that these springs, which are a LOT less expensive than new cartridges, make a big difference.

Are we talking about too much dive on a Bobber or a Bobber Black? I don't notice too much dive on my Bobber Black.

Hi Greybeard

This is on my wishlist and once I've moved house and have a workspace and bikelift (hopefully June/July), will be pulling the trigger.

A couple of quick questions on the TEC springs - they appear to be a like-for-like swap but are any special tools needed beyond a torque wrench and the right size socket (the bike is not with me at the moment so if you can remember the size that would be great)? I note you didn't go with the pre-load adjuster but given the choice would you have done so? Finally, did you change or add any oil when changing the springs?

Apologies for the question spam.

Cheers, Ed

I mentioned elsewhere that I had an extensive test ride on a T120 and the big put off was the fork dive on the lightest touch on the front brake. The Speedmaster doesn't dive at all... I suspect the Bobber maybe similar. Rather than pre-selecting a solution I'd want to go to a suspension specialist to see what options they had..

Same mod done

This was one of the first upgrades I did to my Bobber...It has improved the ride and the fork 'dive' and fitting was a straight swap with no oil change required.
The only thing that was a bit awkward was getting the fork tops back in without cross-threading as they are a fine thread and you do need to apply pressure to compress the spring and start them off.
Just as an aside I'd be interested in anyone who's replaced the rear spring with Hyperpro progressive.
I weigh about 12 stone ( 168 pounds ) so I don't think the cost of a new shock is worth it as I find the ride pretty good 'as is'
