Woke my bike up I have a 13 Gsxr 750 and it made a difference. My bike is straight pipe with no cat. It was lagging really bad in first and second gear. I bought this thinking it would make a difference and it did. I want to say it woke it up and took away about 80% of that problem. I know this doesn't add any horsepower but you can instantly feel the difference. It also tricks the bike into thinking it has two 5th gear. I beleive thats how it gives you more top end. I also dont engine brake as bad when i downshift anymore. What you get out of this for the price you are paying is 100& worth it. July 12, 2016
great product Zbomb made a big difference right off the bat, awsome_ April 20, 2015
Zoom zoom Great product you can definitely feel the difference!!! Well worth it. December 8, 2014
Z-Bomb You can certainly tell a difference in the power. Gears 5 & 6 show 5 as advertised. Haven't had a chance to test out the new top speed but so far so good. Great product for a cheap price. October 6, 2014
awesome Took the shudder out of my busa. Awesome product and very easy to install. August 4, 2014
Fantastic bang for the buck!!! So everything that I've researched on this states that it does not increase power on the Suzuki series of bikes. While I have no way to be 100% certain, it sure doesn't feel like that. It feels way more responsive, and at a higher RPM it opens up like it never has! I don't want to put a PC5/full exhaust yet and I purchased this hoping it would give it a little more kick and it has wildly exceeded my expectations. I'm on a 2012 GSXR 600 and I highly recommend it. It feels more torquey than anything, but I certain feel like I go through the revs faster. For $55.00 I figured if it didnt do much, it's money not really lost. I will say this, the location of the gear position sensor is in a very tight area and I struggled for 30min to get it on. I eventually removed the gas tank bolt, and had my friend hold the gas tank and in less than 30sec I was able to pop it in. April 8, 2014
This product is easily installed Easy to install and well worth the price. Don't know if it actually removes speed gov (don't have anywhere to legally test this) but the decrease in engine braking and increased throttle response is awesome. October 7, 2013
