engine does bear more than a passing resemblance to the ls650 savage, which would probably help with spares and service parts, and would follow the japanese trend of sleeved down larger engines to meet thir 400cc licence rules. but that raises the more desirable thought of a full 650 engine in that frame, iirc the savage is belt drive though. nice looking bike, but as has ben said, the price is a bit high for what is a 20 year old 400cc bike.
