![]() ![]() Together with the Big Red 250 and 250ES, the ATC250R was considered the holy grail of racing, created for recreation and competition. These attributes were not commonplace on other ATCs at the time. This racing machine introduced the market to a 248-/246-cc liquid-cooled powerplant, folding footpegs, and five and six-speed transmission options. The Honda ATC250R was eighth in the line of all-terrain cycles released by Honda since the ground-breaking US90 made its debut in 1970.

Its durability, build quality, and performance made the wheeler appealing to the riding community and consumers in general. ![]() The Honda ATC250R had so much more to offer other than solidifying the presence of ATCs on the racetracks. Featuring Pro-Link suspension, an Enduro-Harley Davidson front aesthetic, and a 70 mph top speed, the ATC250R was tough and fast. The Honda ATC250R (or Big Red 250R) launched in 1981 and was the first to strengthen the foothold of ATCs in racing. It was the perfect racing prototype created in such an inopportune time – only half-resurrected by the TRX250R, its four-wheeled successor that inherited its suspension and engine design. I don't know if buying a $2500 motor is worth it though, when he could have just bought a big bore kit for the original R.The Honda ATC250R was the greatest high-performance three-wheeler ever produced by a big-name manufacturer. I have rode both, and i prefer the CR quad. Performance wise, it will pull on an 89 250R, ported and polished with stock bore, boyesen reeds and rad valve, cool head, FMF Fatty pipe and silencer. ![]() He also had to make his own kicker, and shave the plastics, because the CR kicks backwards, not forwards like an R. He is in the process of fixing that right now.Īs far as the rumors about too much vibration/headshake because there isn't a counterbalancer in the CR motor, I have rode it and it isn't as bad as they make it sound. his mistake was mounting the engine too high in the frame, which caused the chain to LOOSEN, when the rear shock is compressed, it essentially worked backwords of how it should. The whole engine swapping deal also involves lining up the countershaft sprocket with the rear sprocket. Because it was the 87 style frame and swingarm, he had to make brackets similar to the 88-89 style frame and swingarm. It also involved making new engine mounts, which included the rear mount. He spent a lot of time on it, because there is no pipe made to fit the CR's exhaust port in the Cylinder, he had to take his FMF Fatty pipe from the 250R and chop the end off of it, then weld a piece from a CR250 pipe onto it so that it would work. He has an Eddie Sanders head on it(for MicroSprints)and the Boyesen Rad Valve from the original motor. That is probably what the other guy was talking about.Īnyhow, he has an 87 250R chassis with the CR250 motor. However, my friend just bought a CR250R crate motor from a place that builds micro sprint engines. ![]() You can email me direct at if you are interested.Īs far as I know, you cannot buy a 250R crate motor. However, if you are interested I have an 88 250R motor that I just rebuilt top to bottom and I would sell it. As far as the aftermarket frames, unless you find one used you will have a tough time getting ahold of one without waiting for an extremely long time. Most have never been started so they would work OK, but you would either have to fix(I doubt you could) or replace the expensive stator. Now people are getting ahold of them again and trying to pass them as crate motors. They were used for learning purposes, and the stator wires had been cut off of them. Usually, they are 85 ATC 250R engines that were sold to Tech schools way back when Honda quit making the 250R motors. I have seen some people advertise crate motors from time to time, but they aren't really crate motors. You can however, buy all the parts to build a brand new motor but it would be extremely expensive. No, you cannot buy a 250R crate motor from Honda if that is what you are asking. ![]()
