I'm shopping for a new bike It was between a 2016 kx450f or a 2015 , 2016 yz450f. I didn't post this in what bike should I buy section because its not a matter of that. I am looking for Yamaha 450f specific info.  I really like the kx I am very comfortable on it but I have read of motor failures with less then 30 hrs so that really scared me off. . I have always been a blue fan for the reliability and I have never had a problem with any of my yz bikes. I am now leaning towards a 15 , 16 yz450f. I did search around a bit thru the forum and didn't find much so I assume that's a good thing. has the 2015 , 2016 yz450f been a solid bike? it will be a woods bike with an occasional trip to the track. I never had a FI Yamaha bike and to be honest I don't like FI i don't trust electronics.

Buy the FX, not much difference between that and the F and it's built for woods. These bikes are built so much better then their older stuff which was still very good. Yamaha doesn't take shortcuts. These latest gen bikes are very good.

^ that

 

Still a Yamaha, down to the bones. 

Still built like  Yamaha, with a sense of overbuilt-ness throughout, but more refined by a long way over say a 2007 YZ.  Lots of good fittings, brackets, fasteners, wire management, etc.

Nothing like a Eurobike with thier minimalist fasteners, brackets, and fastener sizes, this bike can go end over end down a long downhill and still be fine...

It also does not flex like the Eurobikes either; less compliant but less wander-y at really high speeds too....

More compact than the traditional YZ's, but not as compact as say a Eurobike.

 

This FX is so smooth, refined, and great handling, it makes my previous YZ's and WR-YZ's feel like muscle cars with flat tires.....

 

The plastics above the motor are a bit janky still, even on the 2016 (too many strange pieces, stuff doesn't always line up like it should, etc...) but that's kind of been a Yamaha trait before. 

 

I would not hesitate for a moment to say this is the best of the old school and new school bikes, in one package.

^^ That again.  You want a YZ450 set up for the woods?  Buy the FX, add some bark busters and a more extensive skid plate; Done.

^^^ all that...
Plus you can comfortably unload it at the mx track... and rip it around like an "F" with a few clicks of the suspension.

When I first bought my FX, I spent the first 8 hours on it at the mx track. I absolutely loved it. When I took it into the woods, I felt so comfortable, I was whizzing through tight trees in 3rd gear with no bark busters... I was that comfortable.

Slap on some radiator braces first thing. I cartwheeled mine at the track after a cross rut into a jump. Bent the right radiator, as the shrouds do stick out a bit. Finished the lap. Got back to my truck after inspecting myself, looked over the bike and much to my surprise, nothing else was bent, broke or torn.

Go for it. On my 3rd 450F and they are as reliable as mxa says. I'm getting another one soon, can't decide on the f or fx. Dealer has leftover '16s for a steal. Around 60 hrs on all 3 and the valves never moved, no weird failures, just get on and ride, wash, and repeat. Honda and KTM reliability is a farce.

A new KX450 won't fail at 30 hours. If you don't trust electronics then you shouldn't be riding a motorcycle. Even carb'd bikes have electronics. How do think the bike runs?

2 different dealerships who are kawie dealers told me to stay away from the 16 kx and there are a lot more electronics on a new bike then an ole carbed bike.

My 14' 450f was the same way. After being sprung for my weight and setting the sag it's right where it needs to be.

The 16 kawi 450 has mapping issues, popping and running lean and such as per motocross action. The kawi map tool costs around $700. The yammi does not have mapping issues and the tuner is around $250. Hope that helps

The newest-gen YZF is just a tall bike. I have the same guy/shop do the suspension on all of my bikes and my current 250F is noticeably taller than the previous gen 10-13. Either way, great bikes. I don't have the 450 but as a 250F owner, I have found the current bike to be just as reliable as the older ones.
