Hey guys, I got my bike back in March and it's been driving me nuts with this surging in 2nd and 3rd gears. I contacted five manufacturers of TRE's and all of them came back and said that they haven't been able to make a simple to fit TRE for a 2011 model that retains the factory gear selection indicator. They knew how to do it, but it wasn't user friendly for people to fit without hacking into circuits and things. Then I located a company in Hungary and for a week or two I worked with them to ensure that their product would work properly on a 109. They made a TRE for other Suzuki models but nobody had tested it on a 9 and they had not verified the wiring and connections. I'm pleased to say that the product is awesome. Not only does it look the goods, but it's super easy to install and comes with great instructions. It's a plug and play unit and you only need to locate two wires at the ECM next to the battery and splice into these. The product is called the X-TRE from http://www.healtech-electronics.com/ All of the surging is now gone, the bike is so much better to ride and the gear indicator works as the factory intended it to. I still foung the stock grips to allow road bumps to jar your hand and give some erratic throttle play, but fitting an isolating grip like the Kurakyn ISO grips has totally eliminated that from my bike too. The company has distributors all over the World, just go to the website and you can find the dealers pretty easy. Some are even advertising on fleabay! This mob also makes a speedo healer for the 109 that will give you a perfectly calibrated speedo. It takes all of about ten minutes to fit and is super easy to program. I fitted one last weekend and my speedo is now 100% accurate by my GPS satnav system So finally, great news for all of us riding late 2010 and 2011 models.
