How To Install Nitron Fork Cartridges On A Triumph Speed Twin Motorcycle

[@shuggiehughes2340]

Great video. Thank you. I’ll be referring to this lots when I install my Andreani cartridge kit in the next few weeks.

[@91891Terrell]

This is a great video! It’s clear, precises, and confidence inspiring.

[@3ftDeepChannel]

Thanks, Tererll!

I have a 2022 Speed Twin with the USD forks, and they still sucked. I had GMD Computrack install and set up K-Tech cartridges, springs, oil and fully adjustable fork caps and it went very nicely with the Ohlins shocks that I installed. Gonna get this thing out on track and see how it does.

[@3ftDeepChannel]

Thanks for your comment, Dave. Good luck with the new setup and safe riding.

[@thejonathanrath]

Excellent, thank you. You have far greater acumen than I do. Picking up a '21 black ST very soon...

[@3ftDeepChannel]

Thanks, and good luck with your new machine!

[@Matt-vo1ge]

Really nice video, joy to watch it done so thoroughly. Can I ask if you considered cartridge emulators? If the cost has been worth it? Also, what did you use to clean the threads on the bolts (couldn't work out the material on the grinding machine)?

[@3ftDeepChannel]

I had read good reviews on the cartridges so decided to go that route the emulators look like an inexpensive option to improve the front forks. The bench grinder has a wire wheel that was used to clean the bolt threads.

Great video and editing! ❤

[@3ftDeepChannel]

Hey, thanks!

[@MotoRich1200]

Thanks for the great video - you did an amazing job! Did step by step instructions come with the cartridge kit? Also, any chance you could post in the description the list of tools that you used?

[@3ftDeepChannel]

Thanks for the kind words! Yes, there were detailed instructions with the kit. When we get some free time, we will see if we can post the tools we used. Thanks for your comment.

[@vincentbarlow857]

Great video! What is the jack set up you are using, specifically the frame supports - looks like the perfect jacking solution.

[@mariokasapi8961]

We’re using a “mini motorcycle lift” in the middle (scissor lift), and a standard rear paddock stand. Good luck.

[@chriscarbaugh3936]

Just had a full Nitron suspension installed!

[@3ftDeepChannel]

…and? What are your thoughts about the upgrade?

[@chriscarbaugh3936]

@@3ftDeepChannel to be honest the weather here in Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 has thus far prevented any riding w vigor. Give me a few weeks. Nitron remote res shocks in black are pretty nice.

[@gsd32i]

Hi . I am looking at doing the same front and rear. How do you rate the handling and compliance after a year then.....if you still have the bike? Happy New Year.😁

[@3ftDeepChannel]

I still have the Speed Twin and have no regrets doing the suspension upgrades I think this bike will stick around for a while I still really enjoy it. Thinking back after doing the suspension upgrades I have got used to the improved ride so don't really think about it the bike rides and feels like it should have from the factory no upsets or surprises when riding uneven pavement.

[@gsd32i]

@@3ftDeepChannel Thanks for the reply and nice to see you still enjoy riding the ST, such a shame they put budget suspension on it from the start 👍

[@ohdirtracer]

Nicely done!

[@3ftDeepChannel]

Thanks!

[@michaeljacquemond2864]

Good morning, Do you have a link please to the tool that allows you to attach the kit cap to the fork? nitron tool costs 100 dollars. Thanks

[@3ftDeepChannel]

I used an adjustable pin wrench similar to this www.amazon.ca/Grinder-Adjustable-Spanner-Lock-Nut-Grinders/dp/B07FPGVXTQ?th=1

[@shawnmichael3310]

Thanks for posting. Can you please tell the mm size and total length of the impact driver bit you used on the capscrew?

[@3ftDeepChannel]

I used a 3" long bit can't remember the exact size I think it was 8mm .

[@midi510]

Thanks for making this. Do you know if this is the same for a 2022 Street Scrambler? Could you list the special tools you use? I looked in the description, but didn't see them.

[@3ftDeepChannel]

Sorry, I'm not sure. I'll see if we can post the list of tools in the description, soon. Thanks for your comment.

[@captainbarnicle8548]

Hello. I have a BMW R9T Urban GS. I was told the inside of the forks needs to be machined to get the 22mm TVT cartridge to fit. Have you heard this or have experience doing it? If so, can you provide any specifics on what's needed? Cheers Captain B

[@3ftDeepChannel]

Hello Captain! Sorry, but we don’t have any experience with this. I’d try to get a shop manual for your machine, and confirm with the cartridge manufacturer what is needed to install on your machine. Good luck.

[@volt7cooltangs701]

Great vid thanks. How did the Speed Twin ride after the upgrade? How many hours or days did the upgrade take please?

[@3ftDeepChannel]

After some ride time on them the two things that stand out for me are the reduced fork dive under braking and the compliance on sharp bumps the road shock is absorbed and dampened as the suspension can now react quicker instead of transferring the shock through the bars I didn't realize how much I was bracing when riding on bad pavement I can now feel the front end stay planted. When ordering from Nitron the rider weight is requested on the order form so the cartridges are shipped with the correct spring for your weight. Andreani, K-Tech and Ohlins also make kits for the Speed Twin if you want to look at other options. The cartridges can be done in an afternoon if you have all the tools and some mechanical ability.

[@regmason3128]

Very helpful. Just picked up a 2020 ST with 1k miles. Planning this to be my first mod. Where did you source the specialty tools? Again.. thank you for a great video!

[@3ftDeepChannel]

eBay is our go-to for most things like that, however, if you can get it quicker and easier at your local dealer then try them first. Good luck and thanks for the kind words.

[@duanedragon2]

Thank you.

[@chriscarbaugh3936]

Looks great, but how do you adjust?

[@3ftDeepChannel]

The adjustment screws are located at the top of the cartridge.

[@TheMcCoon]

How do they ride? I’m thinking about doing this same upgrade.

[@3ftDeepChannel]

After some ride time on them at the end of last season the two things that stand out for me are the reduced fork dive under braking and the compliance on sharp bumps the road shock is absorbed and dampened as the suspension can now react quicker instead of transferring the shock through the bars I didn't realize how much I was bracing when riding on bad pavement I can now feel the front end stay planted which makes the rear suspension feel harsh. I'm going to play with the settings to set the sag and fine tune the damping I set everything up as recommended in the instructions that came with the kit. Shortly after installing the cartridges I installed Nitron R1 shocks to complete the suspension upgrades. When ordering Nitron cartridges and shocks rider weight is part of the order form so they are shipped with the correct springs for your weight. It's a shame Triumph cheaped out on the suspension with the Speed Twin as the rest of the bike is brilliant I'm not the lightest guy on the planet and the forks are lightly sprung from the factory so someone lighter might not notice the fork dive as bad as I did. I felt the cartridges are worth the money even though they are not cheap, Andreani and K-Tech also make kits for the Speed Twin. Good Luck.

Good afternoon great teacher. I have a 2009 RXP 255, it was wintered with no problems last year. this year it won't start, the engine runs, the spark plugs work, the injectors work, the petrol reaches the combustion chamber. What do you recommend I check? I wish you good evening

[@3ftDeepChannel]

I assume you mean the end of the turns over but it doesn’t fire. In that case, you should double check your spark plugs. It could be that they are fouled. How did you confirm that your fuel injectors work? What about your coil packs? Have you double checked that they are connected properly? I assumed you have checked the air intake manifold? Nothing could’ve built a nest in there over the winter? It could also be a plugged fuel filter, or bad fuel pump.

[@biagiogiardina7480]

@@3ftDeepChannel Thanks for the reply, New spark plugs, overhauled injectors, overhauled intake manifold. I have a doubt about the fuel pump and how much pressure should it be? When I hit start the engine runs but doesn't give a bang. Greetings

[@3ftDeepChannel]

@@biagiogiardina7480 It's tough to diagnose over the internet. Did you install new spark plugs ? Can you hear the fuel pump run when powered up ? What do you mean by "Overhauled the intake manifold" ? Any codes on the dash ? Fuel pressure should be 58 psi.

[@biagiogiardina7480]

@@3ftDeepChannel Hello Clean intake manifold, new spark plugs, the fuel pump starts with the key inserted, no errors on the dashboard. I'll check the fuel pressure as soon as I can. Regards

[@3ftDeepChannel]

@@biagiogiardina7480 Did you remove the caps from the top of the spark plugs ? I have seen new spark plugs installed with the cap still on and the coil pack will not fit over the larger cap therefore not making contact. Double check all the electrical connectors since you were working on the intake manifold the cam and crank position sensor wiring is in that area and if not fully plugged in there is no signal to the ECU. I'm thinking if the machine ran fine last year it must have been something done since or during winterization.

nice but far too expensive; at the same price you get Ohlins front cartridge and rear shocks 😉

Thanks for your comment, C.G.C.

@@3ftDeepChannel They are certainly beautiful though.

[@lordkryogen]

wow this is way too complicated for the average guy to do, I understand why nitron suggests sending the forks to a service center.

[@3ftDeepChannel]

If an average guy has the right tools, some time and a little patience, he can do it. Thanks for your comment.
