Vrsc Model 1978

Imagine a power roadster like this in 2025: 6 cylinders, a supercharger, the torque of a truck, 250hp... dreams and thrills 02/25/2025 10:12 Rating : 5/5 Respond to Vrsc

Alain81 Model 1978

Superb bike with its magnificent 6-cylinder engine. From memory, its handling wasn't top-notch (in sporty driving). 02/24/2025 18:19 Rating : 5/5 Respond to Alain81

Adri Model 1978

i'm 19 years old, a young biker, and my dream is neither an S1000RR nor an R1M, but this Honda CBX 1000, which was a real revolution in its day, being the first to exceed the 100 hp mark for a production model. It sounded like a dream, and the design was simply sumptuous, with a huge engine block and a clear view of the 6 cylinders - in short, a pleasure for the eyes and ears. 02/21/2025 22:34 Rating : 5/5 Respond to Adri
