I've just returned back home to Finland from my road trip from the Baltic Sea to the Mediterranean with my C5.
The route took me from the Baltic Sea coast of Germany to Malaga in Spain, a total of 1600 miles in 15 days. I was mostly driving on the smaller roads, avoiding the highways and basically any road with a speed limit over 55 mph.
Along the way were some of the very best riding locations in Europe: the Harz mountain range, Thuringian Forest and Black Forest in Germany, through Switzerland from Lake Konstanz to the valley of the river Rhone. In France from Chamonix near Mont Blanc to the Perenees, and the Spanish east coast with its mountainous wine-growing region, all the way to Costa del Sol, almost at Gibraltar.
The Bullet Classic EFI C5 is a solid road bike even for long distance driving. I had no technical problems at all, and all the attention I got was positive. I had about 50 pounds of stuff with me, in the side panniers and on the rear carrier. The average fuel consumption was 65 mpg.
The bike is a 2012 model. When I started my trip it had already 4750 miles on it. For this trip I replaced the original headlight, indicators, brake disc, brake pads and brake shoes. All those parts ordered from Hitchcocks in Britain.
The bike will stay the winter in Spain. Next spring I'll bring it back, this time taking the more easterly route via Italy, Austria, Czech Republic, Poland and the small Baltic countries Lithuania, Latvia and Estonia.
I genuinely recommend Royal Enfield with the UCE engine for long road trips. I don't see how the trip would have been any better with a modern touring bike, like BMW or Triumph, probably less interesting in fact.
