ok. i have to ask this. How does the ninja compare to the speed. Unbiased opinions please. I know the ninja has the same coated crank but is it silicone filled as well. I would get a tko ceramic bearing as well.


ssoooo what are the differences and which one is better.

I am going to buy one of thease.

Price wise the JX is a better deal IMO. The JX has a filled crank but it is not lightened like the speed, which seems to give it a very similar feel on bottom. The JX not hacing the double tungstun weight added spools up quicker and bottom seems a bit more responsive. TKO's are great in the JX, and even with those added it's still less than the speed, hell.... modded it's less than the speed.

so would say the speed is just a little bit better but not really enough to tell. what about the added port? how does it stack up agaist the vspec.

You will be blown away by the JX and the money you save will make you smile. If you are going from a Speed to a JX you will still be happy and the $$$ will be nice. I ran mine for a gallon then put in TKO's and the EB mod button and it flat out flies. I bought the 6mm carb insert from the 8mm to tame it and it still hauls the trash.

truth of the matter is, both are capable of putting you into victory ln, the topend on both are very impressive, yes the 5 port vs 3 shows, but i like the JX because it does act more snappy on bottom, i like that for truggy and 1/8 latemodel.

thank you guys. I was going for the speed but i think you have convinced me otherwise. Now the problem is finding one.

doesn't that contradict? shouldn't the speed have better bottom with the 3 ports? and how does the 5 vs 3 show? sorry if this seems like stupid questions.

i believe the crank not being counterweighted makes the ninja feel stronger on the bottom, i have ran both engines, i prefer the ninja over the speed

the rotating mass and the weight slows down the speed of the rotation, makes it smoother, and higher timing gets the topend going.

+1

i had this tuning trouble the last time so i start from the factory needle setting so far so good .........to dreaux just get the jx21 & ttr2035 or ae pipe it really match IMO you dont need the speed .........save that extra $$$ for something else period

I have the PTM Ninja and run against speeds every week. Trust me, I'd much rather have the jx then a speed myself. It's got great snap on bottom, but doesn't seem to give up anything on top- at least at my track. Over 4 gallons on this one and it's strong as ever. Probably the best motor I've ever owned.

i have a losi re11 will that work well with the ninja?

better case design too. No cracking like the v-spec and speed.. that and the DLC coating is my two favorite things... other then that,, they're all close in comparison as far as power.

is the re-11 the one they compare to the os 2060? if so it will probably work good, i run the 2060 on mine
