I modified an old Yamaha XS 650 for gravel roads and mild off road .
My inspiration was the 1960s Triumph and BSA street scramblers .
I used Kenda 761 tyres ,which I find very good for a medium powered bike , any similar pattern tyre would be suitable .
I used some motocross style handlebars to give good leverage and control at slower speeds .The footpegs on the Yamaha are in a good position for standing up riding and did not need altering .
I put a larger sprocket on the rear to lower the overall gearing and give a slow first gear ,Also I carry the original small sprocket and can change back to that if I have a long stretch of paved roads to ride and need the higher speed.
I raised the seat by adding extra padding and used a sheepskin cover .
The exhaust system was modified to save weight and was raised slightly .
Mudguards [ fenders] were also raised slightly to give extra clearance , the front can be removed very easily in case of "clingy mud" .
Turn signals were relocated to avoid being damaged in the event of dropping the bike .
I don't see anything wrong with a 4 cylinder bike ,but I personally think a single or a twin would be better for long distance touring in remote places .
I think that the key to success would be to change the gearing and riding position so that slow speed riding would be more comfortable and controllable for you .
