actually the story like this, i have a staff, bought a yamaha 150c.c motorcycle by this year january.. every month the tyre sure got at least one time "bocor" then cannot come to work, then few days ago, after the bonus, the next day he told me is timing belt broken, have to take whole day for service, so i'm just curious now the day, is it true for a new motorcycle got so many problem and especially the tyre..
i know nothing about the motorcycle..
actually for cupchai there's no timing belt, but it's timing chain one. it's a small chain that connects crankshaft to the camshaft which will make them move simultaneously on the same time. read more
here. but AFAIK, timing chain should be serviced after 30 000km of use. it's hard to broken unless he rode his bike like rempit one.
about the tyre, take a look if he's using sport rim or rim lidi one. if sport rim, that means he's using tubeless tyre which is known for its durability and hard to bocor one unless he hit potholes often (the tyre will inflate / got 'swollen' at one part). if got the swollen mark, then the tyre is useless.
