George White has a big store in Swindon has new Honda, Kawasaki, Yamaha and Suzuki, clothing there too.
Hein Gericke is usually a good place to shop for gear and accessories; there is a fair few shops in the UK and plenty on your planned route between the Cotswolds and Newcastle.
Unfortunately the time of year means that there won't be any big meets on unless the weather is unseasonably mild. The Foodstop cafe at Quatford, (A442, Kidderminster to Bridgnorth Road) usually has bikes there on a weekend regardless of the weather, the owners are bikers and will make you very welcome. There is also a regular meet at Sherburn In Elmet, just off the A1 close to York although I'm not sure of the exact day.
Give us a shout closer to your visit and I'll check the press to see if I can give you more detail.
We're in the Midlands so give us a shout we may be able to meet for a beer
