Thanks once again for all the suggestions. I had a great trip and my decision to go on my low performance comfortable bike proved to be the right one (ER5) . I almost did the whole trip without any motorways. I did nip onto the M8 to get around Glasgow and on the way back I got fed up with the traffic in Yorkshire so I cut across to the M1 and off again via Matlock. The rest of the trip was great. I went up through the Peak District, got lost and confused around Bolton and Blackburn, escaped back into the countryside again, up and across to Kirkby Lonsdale, over the M6 to Kendal, right through Lakeland to Keswick where I camped at Castlerig Farm campsite. Next day I took back roads up to Carlisle, found the start of the B7078 / B7076 , stopped at Gretna to photograph the Scotland sign then rode all the way to Glasgow on the deserted ex A74 which was absolutely amazing , 80 mph for seemingly ever without any cops , cameras or any other traffic . If I had a supercar this is where I would go to play with it . Once past Glasgow I took the loch Lomond road but immediately came to a halt while a car was extracted from a monster campervan. Had a nice chat with other bikers in the queue and because we were at the front we were let through and had the A82 to ourselves. Next , the Green Welly stop then torrential rain all the way through Glen Coe to Fort William. After that I took the Wester Ross Coastal Trail to Ullapool , camped at Ardmair for two days to rest a bit then up as far as Oldshoremore then did the whole thing pretty much in reverse all the way back to Coventry. Total distance 1620 miles in six days , not bad for an old ER5 rescued from the scrap heap.http://i.imgur.com/ApydLrk.jpg
