I took SBS8517A on 358 (cameo) today.
Quite a smooth ride. Sometimes on euro iv you can see the bar
handle shake very violently but during this trip the vibration was
not apparent.
Maybe it is because it is one of the later batches of euro iv,
which is why the jerking is reduced a lot compared to the 81xx,
82xx series
85xxX series very well-tuned... Much smoother than the 81xxX and
82xxX batch 2 Euro IV KUBs...
Of which 8548 is one of the smoothest. 8547 now a little
rattling...
