The T4 complete package along with the T225 engine class being run in the US are desinged to make karting fun and affordable. As a monobrand, the complete T4 package takes 90% of the kart setup variable out of the equation and really makes the race about the driver. There are a few things you can tinker with (gearing, rear axle length), but even there we encourage racers to share information to make the racing as close as possible. The T225 class allows drivers to use different chassis, which some people feel is an advantage, but the T4 chassis is designed to complement the engine, so we feel it is still the best combination out there. We work hard to keep the category affordable. We set the price based on a reasonable profit level, about 25% at each level, a little more on spare parts, so you shouldn’t see prices rise unfairly. We also put a lot of the proceeds back into prizes and supporting the classes.
I wouldn’t call the engine a GX clone. It’s based on the same geometry, but all of the key components are specially designed for racing and the digital PVL coil and our own Tillotson carburetor makes a big difference in performance. It is also tuned and matched to the T4 chassis to make the whole package feel like as much like 2 stroke racing as possible. Our own world-class drivers made sure it was a kart they would want to drive, not just a cheap kart to save money.
Our goal is to make the racing fun and affordable aroun the world, with the best drivers competeing each year in our T4 World Cup. For the last few years, we’ve been running the World Cup in Ireland, where it’s a little easier to handle the Covid restrictions, but eventually we plan to have it move around to different countries. If you want to see how close the racing was at this year’s race in September, you can see it here: T4 World Cup Day 2 - YouTube It’s the full day of racing, but you can jump to the Finals for each class at the following time stamps:
