So, I'm up to 1500 miles on the bike now since new and still loving it but I have kind of noticed, or rather it feels as if the bike doesn't like doing 60mph in 6th gear. Its as if the engine feels bogged down and is labouring, yet still feels smooth although the engine note changes, I think. Soon as I get to 66 to 68mph the engine changes again and that bogged down feeling goes away. Kind of difficult to explain. I've never had a twin before or a 1300cc bike so was wondering if this is normal. 5th gear at 60mph feels fine. So do I just use 6th for motorways? I'd rather have the better fuel economy when just cruising around. My previous bike was triple that cruised around in 6th easy as low as 35mph without this bogged down feeling. Just wanna make sure there's no niggles with my engine or gearbox. Anyone else noticed this? This is a 2018 bike. Thanks.
