Curious to know. Is it just fashionable or trendy to run an open clutch, or are there any actual advantages? The only one I can think of is it would probably keep your clutch cooler thanks to the extra airflow so maybe less likely to get really hot and sticky in traffic or on very long runs? Thanks!
Upside - sound, keeps the dust clear and runs cooler Downside - drop the bike on the right side while running and clutch and fairing damage is quite likely.
You should worry about water ,the problem is if you put the bike away after water getting into the clutch plates,and don't ride for more than a week or so the plates can stick together with rust. Easy to fix,but a PITA as you find this out when you need to get going!
