TE/TC 2016 te125 or 2017 te150 ????

Heres my dilema... i can pick up a 2016 te125 on sale. I have a fresh 2016 150 sx top end on my work bench. I can swap it out and have a 2016 te150.... Or should i fork out the additional $1500ish for a 2017 with electric start, and explor forks?
In my mind its a plus to have the kehein carb that im familiar with.
It is a negative to have the 4cs forks, though im not familiar with the new explor forks.
The electric start isnt a deal breaker. One less thing to go wrong.
Is one bike much heavier than the other?
Are there major performance differences?

I hate to break it to you.... but your '16 SX top end isn't going to fit on a '16 TE125, as they are different engines. It will fit on a '16 TC125 though. I have a '15 TE125(same engine as '16 TE125) converted to a 150. The 150 in the older engine and is bore and stroke, so you need the crank, as well as the complete top end.

Thank you for that info! You just saved me some grief...

So just to confirm, i can put my 150 cylinder on a 2017 tc125? ... if so, that may be an option too..
Man i love these small bore bikes. I have a '16 150sx. Im thinking i can convert it to offroad and ride the tc on track days...
I wish WB could have worked his voodoo on the ktm motor. My 165 was the best weight to power ratio ever...

Yes the '16 or '17 TC125 will take the 150 cylinder. Walt (WB) did just that to a '16 TC125, before he got his '17 TE150. Walt looked at the possibility of a 165 conversion for the new 150, but the cylinder design only allows a modest overbore. Look at the TE150 threads to see the mods Walt and other riders are having good luck with....
