If so, has there been a real difference in the feel of the ride?  Does it bottom out less then the original shocks?  I've been thinking about upgrading them, but only if it actually makes a difference.

the oem shocks on most scooters are pretty low grade and virtually any replacement will be an improvement in ride and bottoming resistance.

 

even more so if the bike has some ks on the clock, (the small amount of oil inside breaks down)

 

they arent very expensive 4-6k bht i think?

 

i wouldnt hesitate

I upgraded to a pair of YSS shocks. I think they cost me about 4-5000 baht. Well worth it, especially riding 2 up.

My bet also is on YSS shocks ! . . made in thailand and of good quality and comfort.
