Firstly there are a couple of shots of my SR500 THS Phasar
as built by Malcolm in the mid eighties. The bike was horrendously
unreliable - partly my fault for using a knackered SR500, I only used it
because it was cheap, the engine was modified (better oil supply etc.) and
it was fitted with twin front disks. My inspiration (in using a single),
came from Royce's High Techati which I saw whilst he was creating it, and I
still think any engine that is not a single, v-twin or in-line is really
unsuitable for a FF machine - unless it is positioned somewhere away from
the rider. I rode the Z1300 Quasar and I found the riding position really
appalling.
As you can see the SR was a 2-seater and apart from the pillion
footrests being a bit too low it was fine. I found the handling to be
interesting, at speed it was stable and quite nimble (I once overtook a GPZ
900 on a winding country road and the rider was amazed when he found out my
thing was just a SR 500!) but at low speed the long wheelbase and altered
steering geometry made it quite a handful. I did not find the linkages to
be too much of a problem except that the lower tie-bar would clout the
faring while turning. With the air box removed a K&N airfilter was
positioned pointing towards my crutch which was interesting when the motor
spat back!
I used the bike intermittently for a year or so and left it
standing (outside) while I went to the USA for a year. On my return the
thing was in a sorry state and I was in need of instant transport so it had
to go. I sold it to a local guy who was going to try to rebuild it - I
don't think he ever did and I doubt if any parts still remain, but I'll try
to track him down and if they do I'll let you know.
