WR250F Wisco Crank - Working Great For Me

Bought and installed a wiseco crank in my 2005 WR250F with a 290cc bigbore kit almost a year ago and I haven't had any issues with it, even after running it out of oil for 2 hours! (I owe that to Lucas Oil). I race 1-2 harescrambles and enduros a month. I have ridden this thing hard, and she keeps going.

Terrible news

Bought it for an 08 crf250r didnt even have the flywheel on and the threads snapped right off....poorly made I think. So now spending another 300 on a new crank

Great product

I bought this crank for my 03 yz250. I have not had a problem with it and it runs amazing! Wiseco has really stepped up there game with the cranks! I’m currently at 85 hours without an issue! And I’m not gentle!

First time rebuilding bottomend yz450f

This is going to be interesting despite the negative reviews of others with wiseco bottom ends , but so far I have not had any issues with this bottom end , I have rode the bike fairly hard ( 09 yz450f) on track and off and everything has stayed together , now if I was to do it again I would go a different rout do to the number of times I have herd bad things about there bottom ends from bike shops and other reviews . I hope everything goes well with a lot more hours on It, oh and keep your bikes maintained !!

Not sure yet

I had just purchased this crank a week ago, only ran one tank of gas through it, then the rod bearings blew. I didn't even put 2 hours on it, or ride it even remotely hard. Motosport will be shipping me a new one because the part seems to have been defective. Ill install the new one and hopefully it will last much longer than this one.

Excessive play in piston rod

Needle bearings go out.
After 14 hours, needle bearings on crank went out resulting in excessive play in piston rod. I have seen a few of these Wiseco cranks experience similar failure with only a few hours use. Replacing crank is never fun, I was frustrated to encounter this problem, called Wiseco and they said I had to work with Motosport, Kellen at Motosport.com was great to work with and helped out with my return. My advice is to stay away from aftermarket cranks and get OEM.

Q: What kind of rod do you use, Is it a hot rod?

A: Wiseco uses its own designed and manufactured connecting rod. Wiseco has designed these crankshafts and connecting rods to work together with our pistons to provide the smoothest rotating assembly possible. Having a complete bottom end that is made of 100% forged material will give you the piece of mind that your motor will be able to withstand any abuse within reason.
Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
