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.

Garbage!!!

I am a factory trained Suzuki technician and after my first wiseco crank went out they warrantied it and then not even 5hrs later the new one went out again! Absolute junk. I will never buy anything wiseco again.

Great crank kit

2007 CRF 150R. Wiseco did there homework on this kit. It had everything you need to change the crank - the top end kit. Went in easy and fast. I haven't ran it much to know how long it will hold up but so far so good. It is holding up to my son's racing.

Great bottom end kit!

I recently blew my bottom end on my crf 250 and i am only 16 and dont have alot of money. I bought this kit because it was a full rebuild kit and it was cheaper than others. I am very pleased with the performance and power of it i cant keep the front end down with this. I also had never rebuilt a bottom end ever so this was my first time and it was one of the easiest things to do.

Buyer beware

I had this crank installed in my sons CR 125. After .09 hrs of run time the rod bearing on the crank went bad. Wiseco refunded purchase price after a month,but did nothing to help with the cost of installation. In the future I will spend the little extra and go with OEM.

the crank kit installed easily, and performs as expected, but i feel they should include a base and head gasket set, because those are off to get to the crank, right?

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.

A: Unfortunately the aftermarket companies ( Hot Rods and Wiseco ) are not offering a replacement crankshaft for the 2008 KTM 125 EXC. You can either have you stock crank rebuilt with an aftermarket rod kit or you can purchase a new OEM crank from KTM.
