"Dirt Rider", March 1, 2013



Kris Keefer


Think of the iBooster as an in-line ignition modification designed to maximize fuel burn, improve starting and increase horsepower. Simple and relatively easy to install, the iBooster has come under fire from Internet critics who claim there are no performance gains associated with the product. In order to get the straight scoop, I installed iBoosters on Dirt Rider’s 2012 CRF250R and 450R test bikes and also got feedback from other testers who had used iBoosters in the past.

To be honest, the only real improvement that I felt was to the throttle response and bottom-end pull. Coming out of corners I noticed a little better pull and crisper-feeling throttle response on both bikes; the iBooster didn’t hurt midrange to top-end pull, but it also didn’t increase these areas. To me, the feeling of running an iBooster is similar to putting a little race gas in your bike versus super unleaded. Jimmy Lewis had tested an iBooster previously and commented that on some bikes it made starting easier after the second kick, while also changing the jetting on two-strokes and shortening the powerband length. As it stands now, the iBooster is not a modification that will bring massive changes to your bike, but riders who are interested in minor tuning may enjoy seeing how this product can alter their machine’s character.
