OKI the curent piston has 170 houers so im good this season. maybe i will change it in the winter.Keep fresh oil in it and a clean and oiled air filter and you should expect 200-300 hours or more out of it.
And regular valve checks every 50? hours.
A freind has 13,000 miles on his 2010 SM510 with no issues.
But it dipends you oil change gap, air filter condition, , your driving style etc,-What AND 'THE MAINTENANCE HUSQVARNA SMR 450-510 FOR ROAD? (Intended as a max 3 outputs on track annual)
-Oil and oil filter every 1,000 km (15h)
-Valves check every 5 000 km (60h)
-Piston between 12 000 km and 18 000 km
(dependent on usage, I generally recommend to hole engine built up in 15 000 km if not used for peaceful road use)(approximately 150 hours)
-Piston rod, distribution chain, timing chain skate, bearings in transmission between 18 000 and 20 000 km
(I highly recommend you to make this work when you replace the piston) (200h approx)
tnx that help a lotThis is copied in some italian Husqvarna facebook group, that was some Husky mechanic
