The main reason for the 550 engine is that I could make a good bargain with a bike leaning against someone's workshop wall for some years. Most 650 engines are found in SM models and that's rather expensive (wheels, brakes etc). The idea of the Estonian AYR frame is to use as much of the original solo bike as possible but that didn't work out in our case. We would have to make many modifications to fit the Husaberg plastics etc. That's why it's LC4 stuff. Red and white colors, who remembers the Yamaha YZ250 year 1985?
At our level of racing the 550 isn't a real problem, tracks in Finland are short with lots of corners. I was thinking about installing the 105 mm piston. Suspension is very different but typical for AYR compared with other manufacturers. In the back a WP PDS shock in combination with a link system. In the front WP USD fork shortened and modified. The clamps for the front axle and triple clamps are specially made for sidecar mx. It steers very, very light. For a 2-stroke I think it's too light in the front but with the easier going 4-stroke it's perfect. Look at the result list of MX-SC GP-level and check who's using AYR.
