The GP's petrol engines, manufactured by the Great Power Engine of Taiwan, are distinguished by their excellent workmanship, robust construction of high-quality materials and, above all, the use of high-quality components such as pistons, piston pins and connecting rods from subcontractors for motorcycle brands such as Rotax, Yamaha, Honda or Suzuki. Smooth running of the engines is ensured by SKF bearings and reliable fuel delivery by Walbro membrane carburetors. Engines are suitable for operation with both exhaust and tuned exhaust silencers. The well-engineered GP has achieved a very good weight / power / cost ratio.
