Finally got around to constructing a sidecar for my four cylinder faired motorbike. Just like the bike, the pieces used to make the sidecar and its mountings are 100% no later than 1994.
About this creation
I don't know much about sidecars, so this time I googled images of sidecar outfits to get an idea of the proportion of the sidecar relative to the bike and to get a few tips as to how they should be mounted.
This construction utilises my four cylinder faired motorcycle (the MKII version with leading link front suspension) 100% unaltered, with the exception of the removal of the left hand side indicators, whilst all of the mounting points can be removed very easily - there are no changes whatsoever to the chassis of the bike.
View of the mounting points from above. I had to take care to ensure there was still enough room for a rider to operate the left side foot controls. There are five mountings in total - two are extensions of the rider's and pillion's left footpegs, one is a suspending rod from the bike chassis to the underside of the front of the sidecar to keep the nose of the sidecar from dipping, one is a tie rod to the nose of the sidecar to keep it from straying sideways, and one is a tracking rod attached near the bottom of the front of the sidecar. This last one is particularly cunning as it utilises the fractionally angled in beam making the nose of the sidecar to create an almost imperceptible degree of toe-in, just like a real side car outfit will have, and is mounted onto one of the flat "steering arm" plates with a hole facing upwards at the end of it fitted underneath the engine of the bike which was very convenient for this role.
The seat in the sidecar actually performs a cunning role in the sidecar's suspension - its presence keeps the spring from bulging inwards under pressure! With the seat removed, the operation of the sidecar wheel's suspension is far less smooth.
And the view from below. The bike retains it centre stand and kickstand, as the sidecar is intended to be removable.
The sidecar wheel is sprung, and has the same amount of travel as the rear wheel of the bike at a similar rate of stiffness.
On the inboard side of the sidecar, you may notice a lever near the rider's left footpeg - this is meant to be a brake lever for the sidecar wheel's brake, to enable the rider to operate brakes on all three wheels independently. It was a job fitting this in whilst still giving some clearance for the rider's gearshift peg.
Rear view - just to prove it does have a left hand side rear indicator and a tail light on the sidecar.
I was waiting for this one Daniel! :D The sidecar looks very cool and really vintage! I also like the fact you had careful maintaining the original features of the bike that can be used without or with sidecar, and, that the sidecar suspension as similar travel of the bike and both (bike and sidecar) are perfectly aligned. ;)
