Over on the Sportster forums, they are saying about 45 or 46 hp at the back wheel.

Nortons also claimed 60 brochure hp, but only dynoed about 45 at the rear wheel.

Those numbers are a bit slower than the early 70s Commando too.

If it truly had 55hp at the back wheel, it should be faster and quicker than that.

Even with the mufflers removed its still not there....


Torque is strong low down, and falls away as the revs go up, doesn't it.

Be interesting to see the torque curve, that would have to breathe well to make that hp at such low revs (relatively).

What we need is someone who has put one on the dyno.

Where is that Cycle test when you need it..
