Stihl 650?

[Butch(OH)]

Have I missed the dicussion here or is this a brand new model? Never posted a link here before so sorry if you must cut and paste. http://www.stihlusa.com/chainsaws/MS650.html
An economy 660 so it says, hard to figure the need for a cheapo version of the 660.

This is news to me.

Not on the Stihl Canada web site yet.

Basically it's a replacement for the 064. It fills a displacement gap in the Stihl line MS 460 is 76.5 cc MS660 is 91.6 cc new MS 650 is 84.9 cc.

Test report

Just in case anyone is interested, the test report from DLG/KWF is now availiable, see attachment.
I also attach the report on the Husky 385 for comparison.

This was the story I was told by the local dealer. I do not know for fact only repeating what was told to me. I tend to believe this outfit though as they are huge and have their finger on the pulse when it comes to Stihl. Any how what was said is that the new EPA rules has an average rule. So many saws that have to meat the new rules however if you have a bunch that way exceed and a handful are out of compliance it's ok as long as the average per saw sold is ok. I guess stihl has to pay so many $ per saw that goes over the average. The MS 650 is an attempt to get a handful of buyers to look and say the $200 I saved is better than the power and it helps stihl with meeting their compliance #'s. Now this is what I was told and do not make any claims to it's truthfulness however after picking up one of these pigs and running it nothing else makes sense.

it makes some sense to me, just enough to be logical, so I'll believe it. IMO, if I'm gonna spend some money and get a bigger saw, I'll get the 660, and have the larger engine with more power, then have it ported to get the most out of the engine. I want the MOST power for the least weight possible.

huh..... smells like a 575.

I think you`re on the right track Dean.

I m sure with the right modifications it probably will pull pretty well, but when it is virtually identical except for displacement, power and a small amount of price to its bigger brother, then why would people want it. If it weighs the exact same, most users will opt for the one with more power, even if it does cost a little more. The only logical reason is what Dean was saying about emissions targets. It does fill a displacement gap that Stihl had, but it does not fill it with an outstanding saw when compared to its bigger brother.

Look at the 385 it sucks and I like huskys My modded 372 will eat a modded 385 for lunch

 

[stihlwoodcutter]

i've been wondering the same thing about the 650 vs 660.....hmmmmm....same weight less power...75.00 differance......no brainer ...i'd buy the 660

Not my modded 385's. (7.7 HP)

Is that a dyno'd figure???

Yes, yesterday actually. The stock machine yielded 6.2 +/- 0.1. Modified it produced 3.52 lb.ft of torque @ 11500 rpm. This was on a torsion-bar dyno using a Fluke 87 frequency counter to measure angular frequency. This is a very accurate method and removes typical dyno losses like heat, friction etc. from the equation. HP = (2*Pi*RPM*Torque)/33000. (Exactly) Pi~3.1415926535....

I think the same rule applies to auto manufacturers. I seem to recall that the fuel efficiency is a "fleet" thing so Dodge gets away with the Viper by having a bunch of weak cars that get 45mpg. Same thing I guess with the 650 and the 660 or 880.

Me too, sounds logic!

The Dolmar PS-7900 is rated just slightly under the MS650 for power, and weighs a lot less. Probably costs less too. I think the stand out saws in any given top manufacturer's line depends on the largest displacement the manufacturer designs into a given chasis. Stihl's design base being 90cc for the MS660, it's a tough saw to beat. Dolmar's chose 80cc for the PS-7900, so it has best in class power to weight. The Husqvarna 357XP and Stihl MS361 are hard to beat at 60cc. That's why I think it is more important to look at a given class saw than be loyal to one brand, if you're looking for top of class performance.

 

[SawTroll]

You are right about that Tony, no doubt.
It has been like that at least since the 1960ies - different motors on same chassis.
