I've bought a Piranha for my Guzzi V7 Special '23 and it fits very well. In addition as i'm not tall at all (165 cm) it gives me some wind protection above 100 km/h which is better than expected.
So it's a very good purchase i recommend.
Muy buena calidad y el envio muy rapido de Inglaterra a España , lo he puesto en una Kawasaki z650rs y queda perfecto , las instrucciones tenian que ser un poco mejores pero te puedes arreglar.
looks nice on my speed 400, easy fit maybe 30 mins max
Really happy with the product delivery and Dart Marlin screen
