Hi,
Head says UCE/EFI as it's a current model, heart says AVL based on personal experience (and a cry from somewhere deep down in my soul says 1960 Redditch-built Fury, but we'll ignore that for now
).
At the moment all the things most likely to go bang on an Electra-X or AVL Classic can be fixed, i.e. sprag clutches and cam followers, some UK owners have had the big end bearings fail, but if you have a good one you will love it. Bill Harris has just posted about his, which has reached 35,000 miles, so the factory must have been doing something right with them. That said, beware the odd lemon among the peaches, but if the one you're considering has been chugging around quite happily for the last seven years then anything majorly wrong with it should have come to light by now.
Cruising speed depends on what state of tune they're in, but with a good aftermarket carb, unrestricted down-pipe and sporty (but not too open) muffler you will be happy with the result. For town/city riding, if that features in your commuting, drop the counter-shaft sprocket from 18 to 17 teeth, which gives a more responsive bike with little or no drop in top speed. What would your daily mileage be?
Regards,
A.
