If your going to ride all through the year get a bike with decent mudguards. My Z1000 is great fun on my commute in dry weather. It’s a pain in the wet as the hugger offers bugger all protection from spray when it’s raining.
The bike gets very dirty as do my clothes.
Your hands will get cold so good gloves or heated grips are well worth having, if not essential.
I’d go for an upright bike rather than a sportsbike. Better contol and vision for the rush hour, especially if you’re doing a lot of urban miles.
Get something big enough to keep you interested. You’ll think most bikes are quick when you first start riding but you’ll soon start to use more and more of the power and then find you need more.
Don’t race other commuters. It gets silly filtering at 3 figure speeds. Certainly wakes you up though.
