Yes i know there are some hardy soles who do it all year around,
I do say I ride all year round but now, after covid, we can work from home or go into the office so I can pick the (dry) days I want to go in. I used to commute in all weathers, bar snow & high winds, and with good kit (see other thread) it's perfectly doable. I also found it improved my riding and gave much more confidence in the bike/tyres/brakes etc.
The engine has now done nigh on 70k miles and is still strong, although I ride the torque now with just the occasional err... happy throttle moment. It does, however not look it's best with dirt & salt damage a plenty. Whihc reminds me, it'll be needing a oil change & valve check soon.
