Hi All
Can someone help me with a choice of bike for my latest 3 wheel project Im contemplating? Its going to be rear wheel driven ,engine mounted in rear ,two wheels up front,2 seater morganesque.
Im thinking maybe 500cc approx?
Something that hasnt got loads of electrickery gizmos on the engine.
Shaft drive easier to mount as more compact?
Not after blistering speed,just something that will pootle about.
Please Discuss..........
Thanks
Rod.

Just out of interest, if you're having 2 wheels at the front why do you want the engine in the rear? A Morgan has the engine in the front - and very pretty they are too!

or Moto Guzzi v50!
if ya use a cx or guzzi, the engine configuration would give you a similar set up as morgan with engine at front!!!

I described it as Morganesque to give a basic description. Not all Morgans had the engine right at the front,some had it under cover in the front.Dont want all the hassle of the engine mounting/propshaft etc.Easier to transfer a complete bike engine/rearend ,so that it gives me instant drive and rear wheel set up.

So does the 'cx' denote shaft drive?

Yep the CX is a shafty. How about a BMW Boxer. Some of the smaller bikes from the 80's are not expensive. Air cooled so may have issues there if engine fully enclosed.

why a bike?
citroen 2cv or diane,
(try google "lomax" , you will find a 3 wheeler version)
we did a basic one by usin a cv chassis with the rear susp arm turned round to make 1 wheel at the rear,
and i can give you the number of a guy who tunes them VERY successfully,

Looked in to that route,have you seen the prices of reasonable 2cv stuff?  No thanks!  Dslam....I'm thinking a watercooled engine will be better,due to enclosing,then I can just run a duct/scoops from wherever to the fan . P'raps I'll drop the cc size,may have a wider choice then.Got to be complete bike to get all the odds and sods. Does a shaft bike have twin rear springs/shocks,or only on the one side? I think the bike choice is going to be a major stumbling block to sort out,firstly to find a bike,then get someone in the know to look at it for me. Secondly ,I havent a clue about cost yet..going to have look on e bay to get price guides and ideas.cant do much until I have the bike to get ideas on widths for the chassis rails and basic positions of everything.I'm then going to mock it up using 3 x 2 timber for the rails to get an idea of shapes. |

If your considering bike powered, single rear wheel, have you considered rear engined like the Cooper type race cars? You could easily run chain drive which opens up your choices no end. Some shafties have twin shock some have one. Its all dependant on the make/model you choose. Most of the eighties stuff progressed towards single shock.

For info: Rear engined, rear wheel drive: Grinnall made the Scorpion http://www.grinnallcars.com/scorpion-III-sports-car-specification.htmland used the 4 cylinder liquid-cooled BMW K series engine (shaft drive).Tyres were car type, so lots of tread in contact with the road. BMW also made the K75, a 3 cylinder equivalent of 750cc (more responsive than the K100) The Morgan-esque design (engine at front and rear wheel drive) has been done by companies such as Triking and JZR, with engines from Harley V-twins, through Moto Guzzis to the (now rather old) CX500 Honda. Air cooled at the rear would mean having a reasonable air flow to keep temperatures sensible, but at least there wouldn't be a radiator and hoses to deal with. Conversely, liquid cooled at the rear means you don't need good air flow for the engine, just the radiator(s). Engine at the rear could help with traction as the weight will be near the drive wheel, but if you're just going to amble around that doesn't really matter. Personal view is a 500cc could be under-powered, esp if you have a passenger (and most 500 engines are now rather old) Lots to think on, and of course the pennies will influence your choice too.  |
