Just got off the phone with Tom from ESR, and in chatting he told me that Eddie was nearing completion of all new center cases that are direct replacements for the now hard to find, and discontinued Honda pieces. He also said that they are also now beginning the design phase of all new complete and upgraded transmissions that will be able to deal with the power these large displacement engines can produce. That place has amazing resources, and is still very much involved with keeping the 2 strokes alive for the forseable future. With this news, and better than oem design. Who knows how big and reliable the 250R will become? Or, for the guy needing a replacement set due to some bad luck...Ya need not worry and spend good money on someone elses old stripped and damaged cases. They will be here shortly.
