The X3 is another model to the growing list of very reliable mini moto bikes that GRC has produced. Like its design platform the RX, it comes from a long period of design and on track testing. It uses a steel trellis main frame and swing arm and finished it off with a lightweight alloy sub-frame.
The X3 is an excellent bike for the part time racer, or rider who wants a bike that is a good handler as well as reliable but wants to save a bit of there hard earned money, It uses the same frame and dimensions as the RX but does not have all the fancy billet mounts for the brakes or the billet center section that it’s relative the RX incorporates, so if you can handle a little less bling but don’t want to sacrifice quality this is the bike for you. It also shares the same fairing as the RX, so you still get the aggressive GRC look! This bike is also very functional due to the number of engine specs available which makes it able to run in a number of different classes at the race track, and make it an excellent and durable hobby bike as well.
