I have a 2018 F3 Limited with Spyderpops trunk extender. It makes the bike about 4 inches longer. I also have a F4 customs 25 inch windshield with wings. I was thinking the ultragard cover for the 2020 + RTL would fit best. I want the full cover. Anyone try this. I bought a Nelson rigg half cover for F3L and was to short by several inches.
