Famous motorcyclist champion (attempting many races on Yamaha TZ and winner of the Austrian Production championship in 1975 et 1976 on a Laverda-Sulzbacher 1116cc) and above all a high skilled engineer, Franz Laimboeck always kept a deep passion for the Laverda triple, beleiving that it was one of the best large displacement engine to develop for open class racing.

He first conceived the Laverda-Sulzbacher 1200 SC, one of the most powerful roadster at that time (107 hp in 1975), then drew the lines of a Laverda 1300cc engine. By the end of the year, he developed the huge project of the Laverda "nonframe", an ultimate racer built around a highly modified and very fast Laverda triple engine, able to compete the very best racing motorcycles of that time. The particularity of this bike was that it didn't had any frame, using the engine as a stressed member with the suspensions attached at the front and rear.

The fact that Franz Laimboeck succeeded to achieve the huge and very complex 1188cc non-frame project (comprising -F1 pistons, Porsche Carrera cam profile, Alfa-Romeo cup type tappets and many other modifications - and to build one of the fastest bike of that time very quickly gave him the reputation of one of the most renowned rider & engineer of that era.

While developing the non-frame , Franz Laimboeck worked also on a special racer, using another special Laverda engine, installed into a lightweight and robust chassis.

Lack of time and limited sponsoring to build both projects together meant that this second bike was left as a drawing board project only, waiting for better days.

The original project used a Rob North type chassis, known for its light weight and competitiveness. What then would have been more normal than contacting Rob North in person and ask him to build the frame? Rob was interested from the start and began building the jigs – following CAD drawings for the first time.

The frame took shape, built in 24CrMo4, HeliArc welded, using Aircraft spec. material. While typical for the usual Rob North productions, the frame uses the robust engine as a partly stressed member. All that allowed to target a total weight (dry) of 158 kilos.

Even when Laverda was known for its great results in endurance races, Franz is still thinking that the 3 cylinder can be made a very competitive engine for short track racing and GP style of - say - the years 1975/76, so well suited for European classic GP style championships.

The aim of the bike is to perform at best lap times in historic events. This means that tires, brakes, suspension, chassis are at least as important as gearbox along with a very powerful - easy to ride and fast engine.  Everything should be within the technical capabilities and availability of the year 1975.
