Hi Russell
No far from difficult to ride as they had good torque and a fairly wide power band.As has been said you could rev them to 16000 if pushed.The 8 speed box was sweet as a nut and never gave any trouble.Changing up just dab dab dab no clutch needed coming down depended on what gear you wanted as you could withdraw clutch once and hook it down up to 3 gears at once.Of interest when the FIM brought out the 6 gear maximum in 1969 for world championship events the Honda was dead easy to convert as all you had to do was withdraw the 1st and 7th pin from the selector barreland put them back for other events where the rule did not apply.Mind you never remember the scrutineers ever counting the gears so I guess some did'nt bother.
The original CR110 engine had one weakness.The drive side main bearing was triangular outercase shape and had no inner race which meant the caged rollers ran direct on the main crankshaft.This coarsed in extreme cases the shaft to break We overcame this by boring out the outer triangular race and fitting a Ransome& Marles bearing with inner race.Only difficulty you had to drill a hole in the outer cage to match up with the hole in the bored out cage as the bearings have a pressurised oil feed. But it worked well.
