lutz, ye have made me think of what an old seasoned caravanner up here in my neck of the woods told me about the the recommended weight margins for towing. he says that the recommendations came about years ago to give the 85% match in relation to the cars of the day. however, he says that modern cars are way above the capabilities of those from days and the power and torque they provide is more than plenty to accomodate the extra load. i think thats a good point, especially if the recommendations havent been updated.
i can vouch for how much bikes have progressed in the short time of one decade, i have always had one of the latest pocket rockets, the litre class sports bikes. each one i had seemed to take biking into another dimension, and ultimately i have one which pushes out 172 bhp at the back wheel, phenomanal progress, and cars are the same.
would be good idea if the issue was revisited and new benchmarks given in relation to the modern machinery.
