I went through the same thing a couple weeks ago getting my bike ready for storage, so this is all still fresh in my head. For the basics: • A breathable cover is usually good enough — anything that doesn’t trap moisture. • Battery Tender Jr. has worked well for me. • And yeah, a bit of fuel stabilizer goes a long way. While I was doing mine, I found this general storage guide and it actually helped me make sure I didn’t forget the small stuff — things like cleaning the bike properly, topping off the tank, and keeping the battery maintained.

Thanks for the reply. Yes, I'm in the UK. I think I'll do as you suggest and empty the tank. I've already drained the carb bowls. Is it beneficial to start the bike and get it up to temperature every 6 to 8 weeks, or should I just leave it hibernating on the Optimate until Spring? How long to get an aircooled motor up to temperature if just idling / gently revving? 20 mins or so? Thanks again
I leave my bike in the garage with the battery tender going on for a few hours twice a week. I never start the bike until I am ready to use again in the new year. Apart from that I don't do anything else. Being do it this way for years, and never had a problem.
I don't think there's any benefit starting it up every now and then, just leave it on the battery tender, put new fuel in come spring time and press the starter button. It may even do some harm as the oil might then get condensation in it, something cars are known to do if just driven short journeys all the time. I've laid bikes up for decades now on a battery tender after my Fireblade battery went flat once over winter doing the above without any issues. The only other things I do is clean it, drain the tank, coat it in FS365 and put it in a vac bag to avoid getting covered in condensation as our cars are stored in the garage too but as you're storing yours indoors that won't be an issue.
