Advise on seized engine poss

Hi guys I need a bit of advise. Started bike today and got to the top of the road before it made a strange noise, a noise as if my chain had snapped. And bike cut out. Tryed tryed to restart on eletric start but nothing. Tryed on kickstart and kick start won't move. Put bike in gear and bike won't move unless you pull clutch in. Bike as dine about 3000 km.

any ideas on what to check or try.

Take the motor apart and see what happened

Well first I removed the spark plug and it has damage. So went on to strip engine. Found a broken valve and the piston sitting at a funny angle and a crack in the piston crown.

oh shit that's never good full engine failure... You know why it happened? Did you let it warm up before you took off?

Yes I did.

When was the last time the top end was serviced? Ever changed gears or cam chain out?
