Frequently asked questions
Which vehicles can the Kappa 4128SK be fitted to?
According to the Kappa 2026 catalogue, the 4128SK is designed for the Kawasaki Z 650 (2020-2026) and Yamaha MT-03 321 (2020-2026). If you are not sure about your vehicle's version, send us the chassis number and we will check it before shipping.
Are the mounts included?
No. The 4128SK is the flyscreen only. Kappa provides a different mounting kit depending on the vehicle (A4128AK, A2151AK): you will find the correct code in the compatibility table, row by row. The kit is sold separately and without it, the flyscreen cannot be fitted.
How big is the 4128SK flyscreen?
It measures 28 cm in height and 36.5 cm in width, as stated by Kappa in its catalogue. The measurements help you understand how much wind protection it offers compared to the standard one.
Is the 4128SK clear or smoked?
The 4128SK is smoked, meaning it has a darkened screen: it reduces reflections and gives the front end a sportier look. The official Kappa designation is "Smoked flyscreen".
Is it an original Kappa product?
Yes. It is the original Kappa flyscreen with the manufacturer's code 4128SK and EAN 8029871166396, new and in its original packaging. Kappa Moto is a brand of the GIVI S.p.A. group, which designs windscreens, flyscreens and specific mounts for individual motorcycle and scooter models; Kappa products are made in Italy.
How can I check that it is suitable for my vehicle?
Check the compatibility table for your vehicle's make, model, version and years: the 4128SK is listed by Kappa only for those models. If you have any doubts, send us the chassis number or a photo of the front end and we will check it before shipping.
