2014 FZ6R with R6 Front End Conversion


HI everyone,

Seeing as the last R6 front end conversion thread is dead for like 7 years, and no proof or finalization of the finished product, other that some photoshop images that the guy posted, I have decided to do an R6 conversion myself. Also his conversion was on a naked XJ6 essentially, while I intended to do it on a completely full fairing 2014 FZ6R. I did like however, that he listed all the items on his first post, and I will do the same.

The other guy, did an ok job with years, makes and model info. But, I am going to get more in depth on the technical side with dimensions and measurements.
Not only that, but I will be filming the process on my YouTube channel.

The first question you are going to ask is why. Answer: I crashed my FZ6R and bent both front forks and it is something I have been contemplating for a while. Also I am looking for more adjustments in the front end with better braking.

But either way you can expect finalization from my end, either good or bad. Hopefully successful !

Thanks and stay tuned.

R6 Forks Installed to Test for Clearances

Decided not to repair the 2005 R6 forks. It's not cost effective at this time. But that's ok, there's GOLD comin'

2008 Yamaha R6 gold forks

Quick update. So I sent the 2005 R6 top yoke to the UK to get this fitted. It has now arrived back in Canada.

This will allow people using the 2005 R6 top yoke to keep the standard FZ6R 22mm bars, instead of using clip ons.
You can now purchase this item from the Moto-CNC web store. Mine was used as the pattern and I have the first one they have made in the world.






Still waiting on my FZ6R/R6 custom brake lines and front reservoir mount.
Decided to put FZ6R lines back on it for now, and FZ6R front brake master cylinder.
Latest video up with some new Parts from Puig !
