K230UB vibration is due to LTA compliance 60kmh
limiter.Maintenance and tuning is another.I witness and hear how
KUB struggling at highways with noise and vibration all
over.Actually the buses should be better if lock at 65kmh rather
than 60.I feel that the K230s are better with Voith transmission.ZF
aint suitable for them.
In Hong Kong , KMB's K230UB are fitted with European bodywork . I
think they are better than the Singapore SBS 's K203UB with fitted
European bodywork.I don't why SBS K230UB are fitted Malaysian
bodwork. I know the quality of Malaysian bodywork are really poor
beacuse there are so many MAN A 91/A51 with MTRANS MM10 bodywork in
our Hong Kong . I always on board MTRANS MM10 bodywork coach when I
travel to China from Hong Kong . On the ohter hands , Scania K230UB
are not good chassis .They are so noisy when they are in motion
.Their suspension are so poor .But Scania N series are much better
than K series . I am so pleased that KMB ordered ENVIRO 200S from
Alexander Dennis .At least , the suspension of the Aleander Dennis
Darts are much better than K230UB now.
