Erm actually hor on my own opinion lah,... there is no need to
run in lor,... cos its just becos motorshop scare pple drag till
top speed then kana jam... i have a fren ridin KRR came out on the
first day when suddenly he's piston jammed when he's not even
dragin just cruisin at less then 80 km/hr.... but it would be good
that u run in at least 800km if u wanna ride that bike for long
term, if the piston will jammed it will jammed at any speed.... i
change a new block with new original tzr piston with out running in
... went to try my top and nothing happened,been ridin that block
for almost a year and nothing happened yet... u see lor,.... if u
think running in good anot lor maybe by then ure bike power not
that strong anymore... imagine u running at an average RPM of about
6000,... imagine ure piston going up and down for 6000 time per
minute, how much metal particle will be scrap away if u keeps
running at this speed for 1000km or 2000km
...... u decide for ureself lor
