We have learned a lot since doing the first Alligators in 1976 (14 different versions in addition to 36 of the Honda-powered Singles sold to customers). I still love Singles but the latest target is a parallel-Twin built from scratch at AAR. We have begun this project, so stay tuned. It will be exciting just like the Brough Superior was back in the 1920s.
We have done a lot of Twins over the years, all Harley-Davidson architecture and S&S components, but also with many of our own parts and cylinder heads.
The Twins so far:
1) Standard Harley-Davidson Dyna: H-D chassis modified a lot, with a 126-inch, 148-rear-wheel-horsepower engine.
2) V-Gator I: Modified downdraft heads on 111-inch S&S, built and tested.
3) V-Gator II: 126-inch S&S, built and tested (below).
4) V-Gator III: 108-inch S&S, shorter stroke for higher rev limit and less violence in the midrange, coming soon.
5) V-Gator IV: Liquid-cooled, four-valve-per-cylinder AAR cylinder heads, S&S bottom end, coming later.
6) V-Gator D.S.G.: All ours! Parallel-Twin, two counter-rotating crankshafts, with our own gearbox, chassis and body, coming later. It should make quite an impression.
