My razor is 14kw 76v 400a without upgraded brakes (I almost got slimed cuz the brakes)
Make a video with jumps and real dirt i want to build the same one but i don’t think it meant for jumps and dirt btw jumps like 4–5 feet tall but i triend on 48v razor with stock suspension that tooo easy
@Cousinstunts13 my bike is old asf so it doesn’t work for me
I built a razor without e&co parts and I make 80mph
@Cousinstunts13 no i tried dragging my feet but my bike goes back when I hit the gas
My friend just finished his yesterday,I rode the shit out of it
I did put a genuine razor 650 motor on sx500 and no change in speed. The batteries and controller (power delivery) are identical on all 3 bikes
I put the mx650 motor on mx500 and sx500 and didn’t notice a difference 🤔
Only hating that is marketed and typically sold for more when its the same bike. Same battery and same controller. I put 650w motor on mx500 and sx500 and no 500w motor on mx650 and change is speed
@Reel_Adventures_yea he’s wrong it’s 1700+ atleast
Its a modified Razor mx500 running 17kw lol
I got a free 2021 mx500 and a $65 2018 mx650, I like the yellow 😂 but the forks and rear swing arms are rusted and paint chipped, so I’m swapping the back end and front forks from the mx500 over now. basically taking rebuilding the mx650 with all the good stuff. W video
Yes, but its negligible difference when I put 650w motor on my kid sx500 and no change in top speed and torque. Hence the reason for video
Gear it higher. I get 20ish miles ripping it hard and wheelies the whole time
Don’t listen to this guy. They are definitely different in power. I have both brand new out the box and the 650 gets fought over because of the way it handles my weight much better
Razor MX500 almost killed me. I got it out of the box throttle got stuck and crashed me into my garden tool rack full of sharp axes and hoes. 😂
Now you need some better suspension and slightly larger wheels like 12in to lift that thing a little. Then youll be all set. I vuilt one of these a couple years ago it was faster than my talaria was stock.
@BRichSolution i noticed the 650 will pull me better and goes faster than the 500, i did a comparison but at different times it's definitely faster but not $200 faster for $200 you could upgrade controller and motor then another $100-200 48v actually found a deal for 36v bat for $69 might have to do 2 of those and run a 72 v
haha editing the first ride vid as we speak...thing is a freaking BEAST!
Finally!! Can’t wait to see some videos with it out and about!🤟Thing rips😳
i have a mx500 with a 212cc motor on it, thing rips. i’m only on this video trying to see the difference in 650 and 500. size wise. i want a 300 on this puppy😂
@BRichSolution we had 3 mx500 and 3 mx650 in our group of friends and every mx500 we gpsd at 17 mph even and the mx650 varied a little one did 18mph which was mine one did 19mph and one did 20mph even if we switched bikes which is weird so weight didn’t play a factor in that either
Me and my brother have had mx500 and mx650 for years and we’ve raced them countless times gps them too mx650 has slightly higher top speed same torque though but it does pull ahead in top speed even with me weighing 50lbs more than my brother at the time
I would tend agree. I don't have good method of measuring the torque and the manufacturing differences could also be a factor. Ironically when I swapped the old 500w motor for brand new direct razor 650 motor the bikes top speed decreased by 0.5 mph. As for the torque I would say negligible between the 500 and 650. If I have time maybe I can motor swap the 500 & 650 and perform an acceleration test?
Batteries & Controllers are all the same for MX & SX. The MX650 might have 650W vs 500W but I doubt it as I stated in video when I put the 650W motor on my sons SX500 the top speed didn't change and the 500W motor on the MX650 had the same speed.
I have seen brand new mx500 faster than mx650 and vice versa. There is variation in manufacturing. How I suspected the bikes were all the same was last year I replaced the 500w motor on my sons SX500 with factory direct MX650 motor and the top speed was unchanged. The I bought a MX500 & MX650 to prove to myself all the bikes are the same inside (batteries, controller & motor)
yes, the mx650 does 17 mph; the mx500 does the same. The SX500 (green) did 17.6 mph with stock 500w motor; I swapped the motor with a brand new Razor MX650 motor and the top speed dropped to 17.1 mph. That's when it planted the seed for the video. I've seen mx500 faster than mx650 and vise versa. there is slight differences in manufacturing can make a change in performance.
@davidebel9276 The 650 motor has a different sticker. Last year I swapped 500w motor with Razor factory direct 650w motor on my sons bike and there was NO change in top speed and we couldn't notice a change in torque. That's what planted the seed for the this video. Upon opening MX650, MX500 & SX500 the batteries & controllers are all the same. There is slight variation in manufacturing which makes one bike slightly faster than another, but I've seen brand new MX500 faster then MX650 and vise versa
The MX650 and MX500 is the same bike just different colors. If there is a perform ace gain is negligible as I put the 650 motor on my sons SX500 and there was not performance change
from the Y in the seat to foot pegs: SX500 measures 16 inches, MX650 & MX500 is 15 inches As for going to Li-Ion Battery over stock battery. The Stock batteries have 12Ah. The 36V Li-ion battery I used is 16 Ah which is 33% (16/12) more ride time which is over hour. If you go to 20Ah battery you will ride for 90+ minutes
Last year I Installed a Razor factory MX650 motor on my kids SX500 and the performance was unchanged from the 500w motor... that’s when I started to suspect that they were all the same. I recently bought Mx500 and Mx650 and took them apart to to prove to myself that the controller & batteries was the same across all the models. Then I made this video to help others out. There is some slight variation in manufacturing of the motor, hence the reason I’ve seen some Brand new Mx500 faster than mx650’s, but there all about the same top speed
