      Very impressed with the results of installing the DNK tune map on my T120. I didn’t think the bike would perform that much better than it does in it’s standard form.
      I was hesitating about spending the money thinking I’d only see a slight gain but I was happy to be proven wrong.

      I’m extremely happy with the tune file for my 2020 Bud Ekins T120.
      It has totally transformed the way it rides.
      All of the low speed snatchy throttle has gone and there considerably more midrange power.
      It was tailored to my needs with the de-cat, open pipes and free flow air filter.
      It was delivered well within the timescale they said and with the aid of an old android pad and the TuneECU app wears really easy to install.
      If you haven’t done this already then why not?
      Many thanks to DNK TuneWorks.

      A wonderful improvement over my OEM tune for my mods!

    7. Michael Schrock (verified owner)

      Wow! I am blown away by the improvement. Everything is better with the tune. Triumph does there customers a diservice with the factory tuning. I only wish I had done this sooner. Thank you very much.

      The weather cooperated enough the other day to finally take my 2018 out and test my new DNK TuneWorks tune. What a difference. I do a lot of commuting and the low-speed fits and starts of the factory tune are gone. This thing absolutely purrs. Sounds cooler, too! Totally worth the investment. Excellent customer service. They quickly responded to my questions and turned my tuned ECU around in days. Very happy.

      I did not think that the changes would be so significant, it felt like the rain mode was close to the old road mode, and the road mode became just a beast! Thanks Daniel!

      Just got back from a 100 mile ride with my new DNK tune on my 2020 Triumph Bonneville T120 and I couldn’t be happier. The highly irritating “snatchiness’ or ‘spit and sputtering” from 2600-2900 RPMs is GONE. Having put 25k miles on my bike in the last 2 years (x-pipe, British Customs predator pros, DNA air filter), I am very familiar with this problem on the T120, in fact, I originally bought a 2018 T120 and it was so bad that Triumph replaced that bike with my current 2020. So, when I say it’s now gone I know what I’m talking about. The fuel delivery overall feels much smoother & there’s reduced deceleration popping – the engine feels more spirited. My only regret is not doing this sooner. Thanks DNK for a great tune.

      Excellent! From the customer service who very kindly and patiently answered all my questions before ordering, the fast file sending and post installation CS, to the awesome results, far beyond expectations. Absolutely remarkable.

      After allowing my 2020 T120 Black’s warranty to run out and doing some homework on DNK’s Tuneworks tunes, I decided to send my ECU end for the Tune. I had heard good reviews from people who have used the service so figured it was time to see what the hoopla was all about. I was pleasantly surprised how it woke my bike up, it literally runs like a completely different bike. It has much more throttle response and at times, is a challenge to not slide off my bench seat with the new found power. Highly recommend DNK Tuneworks to anyone with a factory ECU flash still loaded on it.
