December 28, 201312 yr guys any ideas on piston suppliers for rotax trials engines, do wiseco do any thing suitable ? going to make a big effort to get bike sorted next year , just stuck at the moment on finding rotax parts since peter knight retired.
January 9, 201412 yr Hi Spud, Genuine pistons were made by ELKO (Austrian firm). Today, no OEM are interested to rebuild such forged pistons. The SWM Rotax engine fit a 18 mm piston crank in various diameter from 54 to 78 mm (depending on capacity). Visit the site www.rotaxsales.be in Belgium (French written) for searching 76 mm pistons. I own a NOS 54,20 mm piston for a TL125. Hope this helps. Cdt, Claudio
