There most certainly is a difference. While H-D does have a presence in the UK, nakeds and sportbikes rule the land there.
I used to be a regular reader of the British Superbike rag...they refer to what is a proper motorbike, and H-D doesn't appear to be it, LOL!
Even though I'm a H-D rider, I like all bikes. In my 20yrs in the saddle, I've ridden a good cross-section of everything out there...and I learned on, rode and owned Japanese for most of those years. After lusting for a Ducati (first 851/888, then 906/996/998 and now 999S/R) for years, I simply got too old for them and their hypersports ilk. I'd love one (999R or Yami R-1LE especially), but I'd get maybe two hours usage a month with my bad back, knee, wrists (carpal tunnel and cubital syndromes), etc. My Hog is big and roomy, allows me to sit straight up and has stretched-out man-sized controls for many, many miles of comfortable riding (not to mention luggage space). 500-600 miles per day in relative comfort (and style!) makes me a happy camper.
In 'ole Blighty, a dearth of open motorway and an abundance of twisty's mean even old codgers like me ride proper sportbikes. Nutter b*st*rds all you lot! LOL! J/K.
Cheers,
Kevin
BTW, Try the H-D Fly and Ride Program...you can arrange a lease Hog in just about every State and some will even give you a free ride to the Dealer from the airport to pick-up your bike. I do it all the time...it works even down-under in the Land Of Oz (Aus). If you fly into SF, you can get the H-D of your choice from Dud Perkins H-D and ride the scenic hour or so up to Alembicland...detouring through Napa/Sonoma, of course (No drinky and ridey at the same time, though), LOL!
