Need Help?? R1 front end questions!!!

I have a 01 and when I bought it, the guy I bought it from had put r6 front end on it. I'm 265lbs and like doing wheelies but I'm scared if I come down hard it'll bend mybtubes.

I'd like to put a R1 front end on it but have some questions I need answered and cant seem to find the answers on here.

1. If i put the r1 front end on do i need to use the r1 rim, rotors and calipers or will my stock ones work?

2. How about the stearing stem.

I'm by no means a mechanic but I do have friends at a bike shop that wanna help.

Any info would be appreciated and my inbox is open.

Thanks

I think you or the previous owner, mean that an R6 REAR SHOCK was installed on it. As far as I know, an R6 front end has never been done.
If I recall correctly, the S1000rr has a REAR shock better suited to your weight. Also a stock shock, properly sprung and valved for your weight would be excellent.

As for the front end... If it's an R1 front, it has upside down forks. If it's a stock front, it has right side up forks.
Either option is just fine for wheelies and your weight, but you do need to get the forks sprung, valved, and built for your weight/wheelies.

If you discover that you have a stock front end, and decide you still want an R1 front end anyways, it's a fair bit of work, ranging from swapping triple trees, to machining steering stems, to possibly swapping calipers, axles, and wheels. It is not a "plug and play" procedure.

Unless you're looking to spend a great bit of time and money on a very low value bike, your most effective solution is to just have your current forks rebuilt, and ride on.

Actually, you can fit R6 RWU forks to a Gen 1. Maybe that's what the OP was referring to ... he was pretty specific mentioning tube bending on landing wheelies.

A good few years ago I fitted R1 forks to my Gen 1 and put together a thread on a UK FZ1 forum. It's probably been superseded by a good few tuners since then but if it helps get you started, yer tiz!

Then it is possible! Just really uncommon? Not sure why dinnering would go through the trouble of doing that and not do R1 forks. Unless the R6 are a direct swap.

Here's another good R1 thread

There you go! FZ1OA comes through again.

I'm told - no personal experience to back it up - that the appropriate year R6 RWU forks have better internals than the OE FZ1 forks (which are pretty basic, in truth) and being slightly shorter, alter the geometry and sharpen up the steering a tad.

As you said, TUF, not a common mod but has been done by a handful in the UK.

Yep, I almost did it to mine. But I really wanted the usd forks for looks.
