Pleasantly laid back singles with quite tough motors, though there are many about running on bodged or non-standard engine components, much to their detriment. If you want to do any serious riding look for one of the later models, whose brakes and handling are more able to cope with modern roads. Properly assembled they should be oil tight and smooth up to 5000 revs, with reasonably quiet engines. Many ended up as trailsters!
