Soft springs are not good news on the bumpy roads around here! Maybe I could just do the same as I did with my first GPZ when we went touring on it. I took off the seat cover and put a couple of layers of foam on the seat, then stretched the cover back over it. It looked a bit odd, but it was many more miles to numb bum!
This one was a gem for retro serenity:
My Kwakker Zephyr 750. Such a joy to ride, with only two faults - firstly it was a bit too low, so the mainstand used to scrape on the road around tight roundabouts, two-up. Then there was the 5 speed gearbox. It was brilliant around town - just put it in 4th and leave it there, but on the motorways and main A-roads I was continually trying to select the non-existent 6th gear. It's funny, really, because on the GPZ I'm always trying to select the non-existent 7th gear!
Seriously, though, although the GPZ is only a 500 twin, when you are in a low gear and get the revs up, at about 8,000 it suddenly bolts away like a turbo kick, straight up to the red line. It's a great feeling (though not for Mrs JD).
I definitely wouldn't say no to another Zephyr, mind.
