I recall when both the RG and the RD came, both road going race reps. They are exhausting to ride though - not just the arguably irrational anxiety of keeping the clutch covered. but the furious flurry of gear changes to desperately keep the needle floating in the tacho’s happy zone. I'll wager if you got hold of either the RG or RD today, once the novelty and the challenge had worn off and the practicalities hit home, you'd be horrified by the wafer-thin powerband, gripless tyres, and rubber band chassis which wouldn't be such fun. we've been spoilt and flattered by the diesels.

Like you, I am utterly astounded by the suggestion by some that today's four strokes are as hard to master. The tyre and chassis technology that was raced in the golden age of two strokes was equally as primitive but exacerbated by massive uncompromising power which was either on or off like a light switch. Either side and you were uncompetitive, too much at once and you were liable to a similar parabolic trajectory as Tim Peake.

The 500s were awful on the front end, due to the fashion for 16" front wheels and the fact that steering dampers were very much in their infancy in the '80s.
As for tyres I was pretty lucky as a mate owned a tyre shop, and supplied me with race compound tyres that were cast in Michelin a/m 59x moulds. I used to get serious looks from guys wondering how I managed to get such amazing grip from Michelin touring tyres that were normally rock hard. LOL
It was a little known fact outside production racing that these tyres actually existed. How on earth did they expect the LC Pro Am series to be so competitive without them? The stuff we did on LCs could never have been done on the road tyres of the day!
Engine wise both bikes were unbelievably reliable, mostly due to Terry Beckett's meticulous balancing and welding of the cranks, and my exclusive use of Castrol A747 2 stroke oil as per his instructions.
Yes their power bands were sharp and could easily catch you out, but Beckett had done amazing work on my bikes as for revs. Both simply revved and revved, still making good power well off the tacho, which helped enormously when cornering as I could hold onto gears much longer.
If you're looking for a nasty bike though, I've got my old CR500 supermoto race bike in the garage. It's pure evil, I swear it wanted to kill me each time I rode it. LOL
You're right though, only someone who hasn't ridden a tuned stroker would even hint that four bangers are more difficult to ride...

It doesnt even have to be finely race tuned. Someone who had ridden virtually any 2 stroke in their life would have never made such an uninformed statement.

Ahh. Bless.
80s tech 2 stroke tuning. When they thought crankcase comp and a narrow pipe meant competitive power.
Still ridiculously good fun, though.

I meant to say something other than an automatic moped buddy. LOL

The swarbrick pipes on my 350 were right fatties. They'd deck out and lift the back wheel if you laid it into a bend a bit too hard. I had to fit a longer rear shock to cure it...

I'd love to ride the RG street bike just to see what it is like. A shame there's none really to be found in the US for any reasonable price.

Abso fuckin lutely, not sure about Saturday though. The looney run to Matlock Bath needed some serious grip or you'd be rolling down the Derbyshire peaks. Not recommended at all. LOL

Ha yeah, always a good run - particularly when approached from the Cat and Fiddle. Haven't been there for years. Last time I did in fact the police were conducted 'random' checks on exhausts, number plates and visors.
