Riding position is a matter of getting used to!
When the 220 was first launched, it was said that you can't ride long distances on it because of its "sport" position. Look where all has it been take today.
Similar story when the R15 was first launched, people said you can't tour on it. Some of the long distance records in the country are being set on this bike now
Its how you adapt to the riding position of the bike, yes a more aggressive riding posture is more stressful but if one is physically fit its possible to take the strain.
