For those of you who are thinking about purchasing a shifter kart or a TAG kart, consider an ICA powered kart. They have more horsepower than TAG karts and because of their simplicity and minimal weight they are as fast or faster than a 125cc shifter kart. They are monsters, and all from 100cc's. Plus, because there is nowhere to race them, they are dirt cheap to buy, albeit a little hard to find. They are also direct drive which is considered by many to be the purest form of karting. Many current and former Formula 1 racers have raced ICA or Junior ICA during their karting careers.
The Formula 100 Karting Series is currently working on introducing a new class, 100cc Senior Pro, that will utilize the ICA engine package along with a spec gear ratio in order to increase reliability and competition among drivers. Keep your eye on their website for more updates on this at http://www.f100karters.com/. Of course in order to race in 100cc Senior Pro drivers will need to possess the appropriate F100 license grade. A Yamaha KT-100 or KPV/HPV engine is a great way to start out in karting and is a perfect stepping stone to a class like 100cc Senior Pro or any other top level karting class.
