[quote="JimFitz"]Hi Bri
I have mounted a Watsonian Monza to my 1960 G12 and I am currently restoring a Sunbeam S7DL to which I will attach a Swallow Jet 80.
You do need to get the gearing right which I did by changing the primary and gearbox sprockets on the G12 - one of my previous threads goes into more details and explains the maths. It is also important to make sure the forks are in good shape because they experience a lot of sideways force with a sidecar and hardly any riding solo apart from heavy braking. The springs also need to be the stronger sidecar type. I have kept the rear shock springs standard on the heaviest setting (Girling type). I only ride solo with an empty chair (apart from a bag of sand to keep the wheel down on lefties) - the springs would need to be uprated for passenger work.
The most difficult task is finding the fittings. Most of the ones on ebay look like they have been dug up from gardens or trawled up from the sea bed and if you can find new ones, are horrendously expensive.
Setting up the sidecar is not too difficult and I did mine with the aid of two aluminium ladder sections, a spirit level and plumb line. There is a guide on the Velorex site which gives typical setup settings to get you on the road - then you may have to tweak them slightly.
Do not forget that you will need to change the registration details with DVLA - section 12 of the V5 IIRC.
Good luck with it.
Many thanks Jim, for the info ive not had a chair on a bike since 1970 ish mind you did do my test on one in 1964 opps showing my age the dvla bit is under the chassis or bodyshell (replaced or modified) i suppose ? ta for that ...but is it not A bolt accessory for a sidecar. did read this below..
A Sidecar such a device, home made or purchased, is considered a motorcycle accessory and is therefore not subject to any approval. It is the equivalent of building a trailer and attaching it to your car. It is the responsibility of the owner to ensure that the sidecar is safely constructed, properly adjusted, matched to the bike and suitable for use on the road.
In the same way a trailer can be too big or badly matched to a towing car making it dangerous to drive; a sidecar can cause the same issues for the motorcycle. Additionally a sidecar affects motorcycle handling and riding style dramatically; it is therefore all the more important that it be constructed properly and with road safety in mind.
thanks im looking to see what section its under ta for the info very helpful.
