If you've ever raced a bike with a featherbed frame, you should know how important the weight distribution is. With a Triton, even though you can get the motor well forward, a manx will always handle better because of where the motor sits. Back in the 50s, there was one Victorian rider who raced a Norvin, and was able to win races against the manxes - why would anyone bother ? A big blast on a vastly over-capacity bike does not prove much. It was something which set a precedent in Australian road racing, and a reason our current historic classes are so stupid. There was a race bike 880JAP/featherbed racing here about 12 years ago, it was not something that I would ever try to ride in a race, a triton is bad enough. It is easy to find yourself in a 70 MPH corner with the bike feeling vague in the front end and twitchy - it really destroys confidence and stuffs your riding technique.
Those sidevalve motors in featherbed frames are the way to go - probably would not bite you.

A couple more examples.

The Fitzpatrick BSA twin.

Another HD engine in a featherbed.

And the Sporton. I think this was a replica featherbed frame built for the Sporton, not an original, but I could be remembering wrong again.

Ken, NEVER apologise for posting stuff like that! That JAPton has to be about the most raw motorcycling experience known to man. Well cool!

C'mon, thats the famous JAP 8/80 Race Engine.

Can still buy them new.
Cameron Racing Engines, Greg Summerton and the late Bob Jolley could all supply them.

Couple of those bikes are well done and nice looking, while the majority of them are pure rubbish

Great pics, I just love Featherbed frames, widelines or slimline don't matter to me, it don't matter what goes into them (hopefully they will be bristish motors) if they are set up right and of course I do mean set up right, they will be one of the best handling bikes on the road, but I think cutting the bottom of the frame away to fit motors is sacerlege (is that how you spell it) to a great frame.
