Brock's 2023 CRF250F with QS138 70H V3 motor and new EM260S controller. First ride 

I build them for customers. This one was $6700, it was his donor bike. He wanted certain things for controller cooling, and I split the battery for faster charging. I could build one for about $6000, you give me a donor. I have a 2008 KTM 250SX street legal, less than 20 miles on it, for $5500

It seems like you are in Arizona?@@dcoxryton

yes I am, Lake Havasu City, AZ Start a private conversation with me, Donald Cox on the Electricdirtriders.com forum. If you are in this area, you can try a bunch of different electrics. KX100, CRF150, YZ250F 2006, YZ250F 2014, KTM 2008 SX,YZ85, an Alta, a Zero DSR

My YZ250F weighed 221lbs with the 42AH battery. I just replaced that battery with a new 50AH battery, I haven't weighed it yet, I will and get the weight to you. I expect 235lbs. The 2023 Honda weighed 143lbs as a donor ready to go, I expect to come in at about 235-240lbs. The Honda is the owners race bike for last year, he just got a new one. Most other donor bike always need all the parts replaced. Rear suspension rebuild is standard, new plastics are easy. front and rear shocks and forks rebuilt. There is a guy in Houston who sells donor bikes, I can't remember his name, when it comes to me, I will send it to you.

Yes it is P42A's. It will be a 20S12P divide into 2 x 20S6P with separate BMS's to control Charge only. The EM260S controller and me will be the low voltage cutoff. The Controller has Soft Undervoltage set at 65V, and undervoltage at 59V, and I don't like the lack of power below 68-69V

With the standard Moto gearing, we get 58-63MPH. That is 13 x 48-50. Look at my most recent RU-vid on the YZ250F That is everything the same as this one, but only 400A. It does not have water cooling.

@@dcoxryton I saw someone hitting 85mph how come this is only 63mph

You can go as fast as you want just change the gearing, but you will have no low speed power. Who goes 85 MPH on a motocross bike. Max speed at the Chicago Super Motocross was mid 60's MPH . You want speed get a street bike.

@@dcoxryton he was hitting 0-30 in 2.3sec btw, and heavier bike than this cos it’s 96v 50ah

its not the same bike lmfao so why would the speed be comparable@@Gabriela-ge7bx

Also do you have the cooling system hooked up and is it needed?

ElectroandCompany.com Their systems rock. You plug them in and they work. Wait till I can pour the Amps to it.

I am mounting the cooling system for the controller now. You only need it if you want to run regularly at 400-450A. The motor doesn't need it yet, but maybe China will come out with a watercooled model.

Your awesome
