Hi Bigpoppa,
I'm located in france;Brittany, and here, the weather is like UK's one

i'm riding my Eva every day for commuting (20k kms), so i'm experiencing (pretty often...) big rains with big winds
ere are my thoughts :
- one of my headlight ballast have been destroyed by a short circuit, this causes the entire headlight to shut off... which is not really a good idea while riding during winter...

TIPS : even with low beam Out of service, you could use your high beams if you switch it ON BEFORE starting the bike.

this issue have been solved very efficiently by energica within the warranty by changing the light and ballast.

TIPS 2 : I put some tape under the headlight to avoid water from washing the interior of the headlight.

- I stick to rain mode when really wet, this is very slippery in sport mode, and already experienced a nearly highside 2-3 times...
my tires are now michelin Road 5 and I love it, perfect for rain and good also for sport/dry road
- the best of raining equipment is a waterproof jacket and waterploof trousers
- Charging AC under soft rain have been fine to me too

, didn't try with heavy rain though
