How much does a top end rebuild cost and what does the top end consist of?

[matteoc414]

I have a Honda CRF 150F and I would like to know what parts make up the top end, and how much do top end rebuilds usually cost, I plan on doing it myself but it would also be nice to know how much it would probably cost if I had to take it to a shop

Impossible to say without some idea of where you are and what's the condition..
Top end is everything above the cylinder. The head, valves, cams, rockers or buckets, valve springs, collets retainers stem seals...

More info is always better. like why do you think it needs a top end rebuild?

A Honda CRF 150F top end rebuild done by a good shop will run somewhere between ¥ 48278.60 and ¥ 241381.00.
