Every now and then a saw comes along that just has "IT".. The 562xp is just that saw... Stock form, it's impressive... Ported correctly, it's a 59cc ball of nasty...
I'll believe you, but it's not coming across in the vids or specs... A 13 lb saw is a bit big for limbing and it doesn't seem to have the torque for the bigger stuff Took the times from the comment section 361- 36 seconds, 372- 33 seconds, 562- 36 seconds, and the 440- 30 seconds. So stock a 44o is 20% faster and the same weight. For the money I'd rather have a346 and 440.
Same crankcase, different crankshaft, different top end and smaller gas tank... The 254xp is the hot rod of that series of saw (254, 257, 261, 262). The 257 was kind of like the 555 to the 562xp or the 545 to the 550xp is today. Same pro grade construction with slightly less performance.
