Is the R1 front forks conversion cost effective now?

Question for my Australian brethren...is the R1 front fork conversion, calipers & brakes worth the effort now?

I've nearly got all my parts together to start my 2010 FZ1 tear-down & rebuild.

I had a quick search for 50mm R1 forks and either I'm not looking in the right place or they are actually hard to find & in a lot of cases, overpriced.

I can understand the reasons for the upgrade, but I'm wondering if it's worth the hassle now.

My main concern is heading down this path & not being able to find all the parts I need.

Some advertised parts seems very expensive atm...how much is too much? I'm happy to pay a fair price, but some seem overly hungry.

Thoughts?
 
The GEN II R1 forks conversion requires at minimum: 04-14 R1 Forks, Calipers + Spacers, Axle+Bolt, Brake lines to MC. Depending on year, you may need a front fender. If you swap the FZ1 Rotors (320mm) with R1 (310) you will not need the spacers.

Like the FZ1, you may need new springs depending on your riding weight. R1 forks are shorter than the FZ1 and will lower the front end affecting steering head angle. You can swap the dogbone to lower the rear or lower the R1 tubes in the triples using an extender cap.

If you can find a complete front end, including the radial master cylinder & reservoir, you have a bit more flexibility. The R1 triples can be used on the FZ1 with some modifications. See Triple Mods on the 'other' site.
 
Here is what I did: 2010 R1 forks with 310mm rotor $450. 2010 R1 6 pot calipers (mint condition $130) 2010 R1 front master cylinder $100. Replaced stock brake lines with steel braided $180. I also added the rear shock and it’s a huge improvement $120. Hope this helps.

I've just purchased a second FZ1 where the guy had already done this, but with 2008 forks/caliper/disks/master cyclinder. It also has an ohlins shock. My plan is to move these onto my FZ1 which already has the engine mods done to it and then resell the second machine as a standard bike. However, he had not really managed the master cylinder reservoir well. This is currently cable tied to the centre of the handle bars (the little hose to the reservoir was pretty long and that is where it ended up). I am interested in what folks have done in relation to properly mounting the reservoir please. Did you use a bracket? - if so, what bracket?. Did you make a bracket? I'd appreciate pics if you are happy to share too.

Cheers.

i find the stock suspension pretty fine. forks and shock. Is it really worth the hassel ?
If you are comfortable with the bikes performance and feel, I would say leave it as is. Why fix what is not broken? Now if you are curious as to the performance or handling difference, it’s much better with the upgrades imo. Brakes are much better and the suspension is more adjustable and smoother. Hope this helps.
