hey guys, i hope this is the right place to post this question

im very happy with my bike but the last year I've been experiencing back pain, i went to the doctor and he said that an old injury i have may be the origin of the pain, he also said that the riding position of sport bikes may be a cause for this type of back pain, that i should "take it easy" with my riding (wtf?)

anyhow, i don't wanna reduce my time on the bike or buy a different one, i love the one i have, so, i started searching and googling for some time and discovered that the cbr500r 2021 has a high clip on from the factory, since that bike and the cbr650r (mine) has the same fork diameter (41mm) I thought that maybe an exchange between the two is possible, but i don't want to risk to spend some money and ruin my bike without at least asking around to other bikers if the know anyone that has tried and succeeded with this, anyone?
