With a Seeley, I know what it does. With any bike, we need to make it work properly. The 850 Commando engine is bullshit. It should not be able to do what it can do. There are plenty of bikes which can be built, but once it is built- that is only the beginning. I would love to see a race class for large capacity retro and classic twin cylinder motorcycles. Racing against a new Enfield with a late or early Commando might not be all bad. However some people are beaten before they begin.
