Speaking of the KUBs, I noticed the EURO 4s have drastically
improved the jerking problems and the gear change is very smooth.
Too bad the speed is still limited. 
Im not sure what KIB that SJE is using. Definitely not a K114IB
because of the radiator and engine sound. A K114 have a different
sound. Cant find the specs of the KIB they are using. It behaved
like K230 actually, and sounded like one, but definitely ran much
faster than a KUB LOL.
Edit: Saw some photos and learnt that its a K230IB. Funny, the
performance is damn different than our dear city K230UB. It even
overtook a volgren bendy with ease and speed. The bus doesnt feel
lack of power, unlike some of our KUBs. Best part: they are not
electronically speed limited.
