Crap! What the heck just happened!?

[RottDude]

2017 Monster 1200, first day I have my new bike, actually that evening, outside air temp around 35 degrees.  Jump on, start it up, take off, and I'm puddling along and just driving around the block.  I go around one corning, at a pretty dang low rpm, maybe 2000 RPM and as I go around the corner the engine stalls and the back tire locks-up, and ass-end starts swinging all over creation!!  I managed to keep the bike vertical, and just left embarrassed and a bit freaked-out...but dang!!  I mean DANG!!  WTF just happened!!

I've been riding M/C's my whole life, and have had a half-dozen street bikes, including two Ducati's, but have NEVER experienced something like that!  With that said, I've never owned a 1200CC twin before, so there's that.

I assumed it was a perfect storm: large jugs, cold engine, cold and thusly a bit slick tarmac.  I'm also assuming this will not happen at a reasonable temperature with warm tires and engine...right

More than likely it's your oil...too thick at that temp...likely a 15w...that temp needs a 10w...running a 20w and it won't even start sub 40

2K rpm is barely above idle.

It has nothing to do with the oil. Cold engine, cold pavement, too low rpm, and it stalled.

Ride it like you stole it.

Assuming the bike started right up after the stall and everything worked well after that I'm with ducpainter.

Yeah, so this line of thinking doesn’t really make sense, and here’s why: I’m thinking that if you go straight and level and slow down that the bike will go well below 2000 RPM before it stalls.  In fact, I’m going to try that this weekend.

With my old ST2 I loved how I could come around a slow corner at very low rev’s and just thump out of it.  I understand this girl has bigger jugs and thus cannot drop quite so much, but now I’m a bit freaked about doing it all right now, cause it wasn’t fun, to say the least.

Could you do it with a cold motor?

First off, you can give the bike a couple minutes to warm up before riding, that'll help a lot.

Agreed.  I believe the cold motor and very cold tires caused the issue.

Also - the compression is MUCH higher on the new bike 

[koko64]

Yes to those suggestions and the ST2 has a tugboat flywheel and crank to keep it turning over. You have a detuned superbike motor.

Congrats on the bike and congrats on keeping it upright during the pucker.   

I think the first number on my tach is a 3.   

Let us know how things go from here. 

Big high compression pistons.
