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.:laugh:

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?

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.

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'

I attempted to purchase the TEC front springs, but they sent an email asking if I had an older model or the newer dual front disc Bobber, I replied newer. They said they don't have springs for my bike and refunded the purchase price (. I looked at Progressive springs and they do not make a set for the 2018 Bobber either, does anyone have any other ideas?

I have a 2018 standard Bobber and have TEC progressive springs installed. They're for the 41mm forks, not the larger Bobber Black 47mm forks.

I installed the progressive zero friction Springs to my standard bobber. I don’t think they have it for the BB. I thought that’s the reason why they upgraded it to 47’s for better performance.

Hi Greybeard, this is going back a bit, but I have just bought this set up and just want to ask if I have to take the unit out from the bottom and drill all the holes in it, or can I just plug and play the emulator/springs and adjuster?
Thanks

I installed the TEC progressive springs by removing the nut on top of each fork, pulling out the factory spring and dropping in the replacement. Pretty straight forward. Just be sure to have the bike properly supported, so it doesn't drop down when you remove the top nut or things will likely be a cluster-fark.

Is the tec front a good match to the wilbers rear? Has anyone done this?
I have the Wilbers rear shock and TEC progressive front springs with preload adjusters. I didn’t go with the cartridge emulators but the springs are better and handy being able to set the front preload sag to my weight.

Do you both have the adjusters or just Jimijam? I can really feel the change in ride from comfort to sport when adjusting the Wilbers. Is it the. Same with the tek or less so?

Ignoring the money, would the cartidge be a better option? Do you have to take apart the bottom of the right shock to get the old cartridge out, or is it all done from the top?

I believe you have to take the forks apart for the emulators including some cutting and drilling. The progressive springs are a straight swap from the top and the pre load adjusters went on as the normal caps would. I’m on the heavier side and had too much sag with oem setup which is why I added the adjusters to raise the front a bit to ~ 30mm ride height sag and have since not adjusted again. Difference being front end not bottoming out anymore over large bumps and less brake dive. With the wilbers a much better ride over stock.
