That is a strange one - only some of the online reviews mention this & others say it is light. Not seen any mention of the Meteor clutch being heavy (skimming a Meteor first ride write-up in Motorcycle Sport & Leisure last night stated a very light clutch) and the Meteor & Classic share the same engine unit. Something to check out on a test ride, as one person's "heavy" can be another person's "light".
By comparison the CB 350 in India is better all round.
Yet there seems to be little love for the CB350 in it's home market ? Partly down to a decision to sell it through a limited number of what the Indians call "Big Wing" premium Honda outlets, but the engine gets critisism for lacking bottom end torque. It is a nice looking thing, though not actually a lot more performance than the new RE 350 platform. It has apparently already made it to the Japanese market & if the Meteor / Classic 350s take off here, who knows if we may get it as well ?
I think for UK roads it would be better to go Interceptor if an RE is what you fancy.
Very different animals, though. I get where you are coming from WRT to performance capability for mixing it with heavy traffic on faster roads. But the twins "feel" very different to a single - busier, more urgent, but mine also takes more out of me than the more pedestrian single. My Classic 500 is more relaxing to ride on slower roads than my Interceptor & I can do more time in the saddle & cover more distance with less fatigue on the slower bike. This is mainly down to my knackered hands - I felt worse after 250 miles over 2 days on the twin last weekend than I did after 350 miles over 2 days on the single last month - just down to accelerating more slowly & travelling 10 mph slower generally. No less fun, though - just a different experience.
As I just ride for pleasure, I can choose the roads to ride to suit the slower bike & I guess a lot of Meteor / Classic 350 buyers will be looking for something similar. That these bikes are a couple of thousand cheaper than the twins may also count for some - a lot for bike for around £4K (cheaper than some basic Japanese 125s).
Nice to have a choice, though.
