The TPC BBR (Big Bore R) is the perfect chassis for the 250R engine with Big Bore Cylinders. For years the Honda 250R engine has had a variety of options when it comes to big bore cylinders. The problem has always been that while some fit inside the old ATC frame, many others did not as they were built more for the TRX Frame. Additionally, the old ATC chassis was not well suited to handle all the extra power these big cylinders could produce. From the small conventional forks to the old school backbone frame that flexed too much and often cracked, and just the general small size, the ATC chassis showed its limitations. TPC has the answer to these problems. Based off the legendary TPC 450R chassis, with its twin spar frame, massive inverted forks and proven geometry, the TPC BBR can handle all the two stroke power you dare to put in it, in a chassis that can be lighter than the old ATC 250R. TPC 363R as pictured above is 285 lbs. The TPC BBR along with the TPC 250X represents the next evolution in TCP Trikes utilizing our full-frame technology.
