Fork emulators and adaptors for Triumph 41mm forks

I was hoping for some improvement in the feel of the bike (2017 Triumph Street Twin) but was delighted with the actual result. Much more comfortable and less tiring to ride. I set the emulator spring to two turns of compression and used Motul 10W fork oil and retained the standard springs. The bike has also lost its tendency to "fall" into corners although this may be more due to getting the preload set correctly. I had to make a tool before I could remove the damper bolts and also to allow me to re-torque them on re-assembly - see pic. I think a few simple instructions would be useful with the package.

I would firstly like to say what great service I received from Tec Parts. My order was taken and delivered in 5 days from the UK to Perth Western Australia. The emulators are a simple poppet type valve at a good price. I fitted the full kit, progressive springs and preload adjusters. I cut down the spacer by 25mm so I could fine tune the bike/rider sag for my weight. The fitting and damper modifications can be found on Tec Parts YouTube channel as fitting instructions don't come with the YSS emulators. I recommend the the full kit which comes at a great price and the great service from Tec Bike Parts

As ever excellent service, parts work like a dream. I,ve had full exhaust system, shocks and now fork upgrade. All have helped transform the Bonneville. Can,t recommend TEC enough.

Fed up with the poor triumph front suspension I previously fitted the progressive springs which made a slight improvement but the action was still very poor. Decided on the emulators as they had made a reasonable difference to a friends America. Instructions could be a little clearer and there needs to be a bit of actual setting information if you want to adjust the emulator. But. The improvement in performance is amazing on the SE. basically the suspension now works. My bike may need a little more preload but that’s a minor issue. Beware. The bolts holding the sliders were very tight and I needed to use an impact gun with the forks compressed with a ratchet strap. A definite mod to all SEs.

Just to say thanks for the quick delivery, cheers Keith.

Transformative. There are certain things that MUST be done to Bonnevilles and this is one of them. Washboard roads were causing my forks to go solid. When you look at the video you understand why. This absoloutely fixed that problem. It suggests you cut down the internal tube as well but I didnt. This has given me the perfect amount of pre load for my weight. 95kg. Thanks Tec.

Parts were well packaged and arrived in good time. Great that there is a YouTube channel to help with fitting and that Tec went to the trouble of testing the parts and then adding 2 plastic rings to ensure the parts work...which a.n.other suspension specialist does not supply/even know they are required

Bought these for my 2020 street scrambler, unfortunately they don't fit this model because it has forks with damper rod in right leg.

Great products and even better support. Many thanks.

got fork elmiators for a friend to fit his boni, so cannot really comment on them but being a generic kit for different makes, he said reading instructions are not very clear. it would be nice to see at least a basic fitting guide what to alter ect, yes I know there's a video but he has no Internet

Last year fitted TEC progressive springs and this improved my Bonneville Newchurch ride noticeably. This year I fitted the emulators and it really does feel like a different bike. It's a much easier ride and better planted. The biggest benefit seems to be that the rear shocks now work better, presumably because they are not having to do so much of the work and perhaps not being pre-compressed by the original primitive front end every time I hit a bump. I think the compression adjusters would be a useful add on now to get the balance right.

Fitted these valves from a specialist of suspensions and the bike is responding perfectly no more issues and lack of confidence that you can't trust to the motorbike on going very cautious on braking and bending now is a proper bike my forks are fully Tec upgraded with progressive springs, valves and adjustable endcap and rear suspensions worth the money guaranteed!!

I had previously fitted the TEC front and rear progressive suspension to my 2011 Bonneville SE, as the original factory fitted are just awful. After about a year, I really was finding the front end too hard when driving over unexpected potholes, or even speed bumps. Made for dangerous driving. Just fitted the Emulators and Top adjusters. WHAT A HUGE IMPROVEMENT. I took the forks off to do the job as I was changing fork oil at same time, and it really made the job easy with forks off, especially managing those nasty little bolts that hold the dampers in. I had an air gun but couldn't get one of the bolts to undo. The trusty short broom handle down the tube did the job with no effort. TEC recommended 7.5W light fork oil which I did put in. The instruction video is for Scrambler with extended forks, so I tried with fork oil level at about 130mm below fork top, and this seems OK. With the top adjusters it means it's not so critical as I can preload or not to get perfect feel. Once again great product from TEC. A shame that the Triumph designers chose to put such rubbish suspension on in the first place. 2011 Bonny SE

Extremely fast delivery delivery to the other side of the planet. Great products. Only slight disappointment that the was no instructions for the figment of the fork emulators. Thanks

The emulators were delivered very quickly. There were YSS instructions in the kit of how many holes and what size they need to be to take the existing damping tubes out of the equation. They are beautifully engineered. Fitting them is straightforward. Tec answered my email about reducing the spacer length to allow for the emulators and the adaptor rings provided by Tec. They answered promptly that 20mm needs to be cut off. I haven't tried them as the bike is still in bits but all reports that I have read say that they make a big improvement over the stock system.

My bonneville now handles much much better now thank you very much for help and advice

Fitted these to a 2007 America. Installation is pretty straight forward, the only minor gripe is that the adapters are a loose fit so keeping them in place during reassembly is a pain.Certainly has improved high speed damping, but as i did a full rebuild on the forks so its a little early to appraise overall performance.

Front end is more positive over rough road surfaces and dips more steady, under heavy use of front brake. You will need a sharp hacksaw blade and a good eye, when you shorten the spring spacers to accommodate the emulators. ( you won’t get the top nuts back in, if you don’t cut them) No need for a full strip- just drain the old oil and remove the spring and spacer.

Providing you have basic mechanical ability, you're only going to make the standard forks better. I installed these with Hagon progressive springs & TEC Fork top pre load adjusters for Triumph 41mm forks. 2011 T100 much better now.

I have not fitted these parts yet but they look very well made ! I don't see any problem fitting as I've fitted rear shocks from TEC and they work very well Delivery was ver fast received within 2 days of placing order Cheers

Excellent improvement in the speedmaster front suspension, fitted the fork emulators, drilled the damping rods and used 15w oil, really happy with the result.

As you said the best initial mod for my Bonneville forks. Could not believe the difference I can now at least feel what the fronts doing and look forward to some descent weather me to enjoy the bike even more. Thanks TEC I,ll be back for the rear shocks very soon.

I've just got and installed the emulators at the moment, didn't wont to do to much in one got. As I wanted to see the difference in each stage changes. kept the same oil what was in there for now, and there is a difference to the ride, it takes the harsh damping out, so all good. will be getting the progressive springs latter, then the rear shocks. riding the 2018 steetcup.

I´d allready installed emulators, progressive springs and preload adjusters, change oil to SAE 7,5. Tried just on short track, because of weather, but I feel huge difference. I´ll play little bit with preload. Allready installed TEC rear adjustable shocks, rebel 2-1. Thank you TEC for suggestions and advices, that helped me to change my bike. :-) Extraordinary services

Hi, not fitted the emulators yet, but have TEC springs and preload adjusters, that work great. With TEC rear adjustable shocks. Have had lots of parts from TEC bike parts, all good quality and great service. Thanks, Kurt / Sheila.

Nice product easy to adjust

Great reviews, as of yet I haven't fitted it yet, but looking forward to that..

What difference - makes you wonder why they build the forks that they do when some small parts can change the whole feeling of the bike

Great product and very good service

YSS fork valves are fine but two black plastic spacers are poor quality.

Quick service and excellent products as described. I have purchased many TEC products for my 2010 T100 Bonnie over the last few years, they are always great investments and clearly thought out, benefitting the performance and looks of the bike. The online guides and customer service are a brilliant help for less experienced mechanics, like myself and give full confidence to attempt doing any work on the bike yourself. Great job TEC thank you. Nicholas, Brighton UK

What a change, front end now glides along. Such an improvement. Just handles the bumps and rough roads so well. I am a light rider and so i could tune to my weight. Used with 10w oil. Transformation. Thank you

wow what a great improvement ... getting the damper rod bolt out was 'fun' [used the broom-handle method] but all well worth the trouble ... now riding it feels like all the roads have been re-surfaced ..!! all in all a very confidence inspiring option ... only wished I'd done it a long time ago.

Wow is the first word that will come to you. I also fitted their upgraded springs and pre-load adjusters. These covered my Christmas presents Not difficult to fit. Took a morning with tea breaks. Took the opportunity to personalize for my weight. Best mod I've done so far.

I'm used to sports bikes but thought I'd try to make my Triumph America handle as good as possible for a big cruiser it had decent rear shocks and progressive fork springs fitted when I bought it but the front end was vague and the fork damping was typically harsh and gave little feel or feedback so I fitted these emulators with fork pre- load/ride height adjusters and it feels like a different bike lean into a corner and you can feel where the front wheel and the tyre grip is through the bars and the bike feels surprisingly nimble, responsive and safe to throw around. With the pre- load/ride height adjusters the bike sits lower and the forks now have free sag and the bike sits on the progressive springs and reacts well to small bumps and rumble strips which now feel like controlled ripples that don't rattle your teeth, throwing the bike through some fast chicanes it remains planted, controlled and on line and I've had to change my riding style as before the bike tended to under steer because of the vague front end and not wanting to push it you tended to wait and let it find it's own way round a corner but now you can choose a tight line and hold it then pick it up and throw it the other way with surprising lean angle and no drama, it's easy to underestimate how poor most standard suspension is until you ride a well set up bike and I've been surprised how well the handling and ride confort has been improved on this heavy cruiser it's a small price for a big improvement in handling and ride quality. Caution using an airgun to undo damper rod bolts the airgun spun one damper rod inside the white plastic/nylon bush 'Triumph call them 'Oil Locks' and damaged the bush which caused the fork tube to lock up in the fork slider when tightening the damper rod bolt on reassembly and I had to buy a new bush.

Great and easy way to upgrade forks ..... good quality and price. Also bought the progressive springs. Thanks Tec !!
