Do I have useful experience to add....not really but hey ho....that hasn't stopped anybody else...
I rode the Rickman at Carole last September and got comprehensively buzzed by a young lady on a RE Interceptor! (I may have been on my Suzuki which constitutes my excuse!)
I would doubt it was standard, and certainly I could see uprated shocks.
That wasn't long before visiting a local fellow Brit and former classic Ducati racer who has a motorcycle workshop serving locals and not so locals.
He used to be a Guzzi franchisee in the UK. You can't move in his workshop for bikes, including his own Guzzi and T140 and several smaller bikes of his wife's.
He had a Commando on the bench that he was doing a lovely restoration to for someone. And had an RE 650 on another bench he was in the process of converting for a customer to towards 900cc with off the shelf kit parts. He happily pointed out the low budget cycle parts.
But he also said....'I've ridden a couple, standard and modified', 'these are really good for the money' and 'you should get one'....
He had bought a smaller RE for his wife, but he isn't a franchise.
Later in the year a contact who built some very successful racers in the UK died from cancer. He had an RE that he made his last motorcycle ride on. He loved it and regularly told me so!
And after reading your post last night, I bloody dream't I had actually bought one with the money my wife wants to use to buy her a car! That won't be happening then!
