Red Valley Motorsport Amplux
Red Valley Motorsport Amplux based on a Yamaha RD250
Tony Helmholt took a 1975 Yamaha RD250 with a blown motor and began working on converting it to electric. The Amplux uses a 36V Etek motor, three 12 volt lead acid batteries and a 6 speed gear box to achieve 91 mph top speed and a 24 mile range. It has a fully programmable speed controller which is updated using a laptop connected to the electronics in the bike. Custom 200 LED headlights keep draw low for the lighting system. Tony is working on an updated version with a fully customized frame and twice the power and range.
Look for Tony and the Red Valley Motorsport Amplux this weekend at the eGrandPrix 7/24 to 7/26 at Vintage Motorcycle Days. Here is a video of the bike in action.
