Picked up a 1900Kv to try versus the 2050Kv I have been using in my 1/8 buggy for a bit smoother low end.

When I turn by hand the shaft, the 2050Kv feels significantly more "notchy". Is this normal?

been awhile since I had a 1900 so I don't know how it should feel.

Also, what are the bearing sizes in the motors?

Coming up on 1 year and no answers for ya. The bearing size is listed on their site. i'm wondering though what you've found as far as difference?

Never tried out the 1900kv motor only a 2200kv and 2100kv . The noticeble diffrence for sure would be much smoother bottom end with the 2050kv with lots more top end speed .

Il tell you this I like the 2200kv with the punch control down than the 2100kv much easier to drive with. The 2100kv has some torque on a buggy regardless .

Still want to get a 1900kv to see .

No the bearings should not feel Griddy in the motor . Acer sells some good motor bearings get cemetric ones smooth as hell .

Yes, the Tekin 2050 turns much harder both by hand and on the track. It's no where near as smooth off the bottom as a 1900Kv motor. When I first tried a 2050 I thought the sensor board was bad because it was so peaky off the bottom. I put my 1900 sensor board and sensor wire in the 2050 just to be sure and it was still that way. I've talked to other racers who feel the same way about that motor. Even my 2000Kv truggy motor is much smoother than the 2050 buggy motor. All the T8 motors take 5x11x5 (rear) and 5x16x5 (front) bearings.

I'm running an mmp and was gonna buy the first good used 1900 or 2050 I saw. First guy that contacted me was a 1900kv and kinda glad cause I'm reading it pulls a notable amount less amps.

wow blast from the past lol.

From what I can tell, the 2050 hits much harder than the 1900. 1900 has plenty of torque though.

What about 2000? Is it something like compromise between 1900 and 2050 at torque and top end? How smooth is it compared to 1900 and 2050?
Why is 2000 bigger than 2050?

The 2000Kv Truggy motor in my opinion is as smooth as the 1900Kv buggy motor. It's a longer can/rotor, so it has more torque than a 1900Kv buggy motor and it has slightly more top end. Despite the extra torque, it's still a really nice smooth pull off the bottom. The trade off is that it's a heavier motor, not that most of us will notice that. I keep a 2000Kv truggy motor in my spares box because it can be used in either my buggy or truggy. Well, unless you have a Serpent 1/8 buggy which doesn't have the room to fit the longer truggy motor.
