    l'm seeking advice on whether an rgs swingarm (on e-bay) will fit my frame, (no. 7265) and what would be the best type

    of forks to use, for a trackday bike, any advice gratefully received,

                      thanks eric
 
Swing arm will sort of fit Eric, it will require machining to fit into the earlier frame. The pivot width must be reduced and the bearing receses bored deeper. You will also require a longer chain.
As for forks the world is your tasty bivalve mollusc. The originals can be made to work fairly well.

        Thanks, it's a lav 1000 triple frame, l have access to an aerospace workshop facility, so any machining, or welding, is "within my

        compass" it,s not having the experience of knowing the best "bits" to go for,what about GSXR swingarms and wheels? are they for

        more rubber? l'm just in the process of beefing up the headstock.

                  thanks again eric

'85-'87 18" GSXR1100 wheels allow use of modern radial tubeless tyres, are much lighter and stronger than the Laverda wheels, and are relatively easy to adapt. The twin shock GSXR swingarms from the same period aren't really any more substantial than the RGS arm, and are way too wide. The trickiest thing is the chain line on Laverdas, which usually limits you to 130 rear rubber for the chain to clear the tyre. If you use a 520 chain and sprockets offset to the outside you may get as wide as a 150 on the rear (depends on wheel and tyre make), but it'll be very close.
Don't forget if you use Suzuki wheels you also need to adapt the brakes. You can get adapters for 4-piston Brembos at the front (and light twin piston caliper at the back) from a couple of sources, notably Keith Nairn and SFCPiet installing Redax Engineering bits from Australia. The Suzuki wheels are starting to get very hard to find, but they're still available if you look long enough. You have to machine the front wheel to accept an adapter for the speedo drive, and also take quite a bit off the sprocket carrier to get the chain to line up.

i'd be interested to see a few pics of the 'beefing up', eric, if you could.
 
      No pics' yet, but l intend using Andy Wagners gusset plates, they look very 'burly' items, l'm fairly 'burly' myself.
