Planning on a 2006 R1 front end swap ...what to i need to know

Bearing sizes. In this case, differing sizes between the top bearings. May be able to press out the stem and use a correct size Honda stem.

you need to know how much steering lock you might loose when fatter fork tubes bump the frame, like this bike with 929 forks that is an unrideable showbike and won't steer more than 15 degrees left or right of center.

not all modifications result in improvements !
i still don't see the need for any front end designed to handle a 180mph superbike on a hawk that won't go much over 115, especially since the hawk front end can easily be improved without messing up the geometry or changing steering ability.Last edited by squirrelman; 12-03-2021, 07:11 PM."It's only getting worse."

This…
I went w/CBR600RR USD forks on my Hawk. While I like the look, in retrospect I should have stayed w/the RSU fork and improved them w/emulators. While my Hawk is a blast to ride, the handling of my quasi stock CB-1 is far and away superior in its handling characteristics. Having never ridden a truly ‘stock’ Hawk, I can only imagine the handling was on par w/the -1 at time of manufacture. Sometimes appearance isn’t necessarily the best choice at the end of the day. Read and learn from others…

Our Hawks have all the power any mature, sensible rider can use on any street or highway without carrying around excessively unnecessary big-bore weight and power - squirrelman
Bike builds can be and most time are art and expression. To take something mass produced and impersonal and make something personal that you can't stop staring at as you walk away. There is nothing I find more satisfying than looking at something cool and beautiful and thinking "I made that". - 6Comment

And the other things that go with any new front end (not all will apply):- Losing speedo drive
- Losing gauge mounts
- Losing Headlight mount
- Losing Turn signal mounts
- Handle bars
- Length of electric control cables
- Length/routing of clutch, throttle, and choke cables
- Length/routing of brake line(s)
- Incompatible ignition mount/custom wiring if using a non-Hawk ignition switch
- Incompatible steering lock - as in security not turning radius
- Also (and already mentioned) the Austin Powers turning radius
- No longer having a matching key set (gas/trunk/ignition)
I'm not saying to do it or not but these are some of the things that you need to know.
You should make a list of what you want and why. And be as honest with yourself as possible.
If it's just for looks that's fine and up to you -- just be honest so it helps when you have to modify the plan due to a roadblock.
If it's because a non-adjustable damper rod front end is not that good then be aware of all the other ways that that can be fixed.
If it's just to make your street bike handle a little/a lot better than it did then springs, emulators, and tube height adjustment can be had for a little more than $200.
If you want different rubber and don't want to mount a 120 tire on a stock Hawk wheel then there are solutions for that also.
If it's because you already have (or have an opportunity to get) a cheap R1 front end, then be aware of how quickly the ancillary costs will eclipse the initial cost of the front end.
If you were looking for a support group you're barking up the wrong tree. This place is fulla enablers dude. - Shooter77us

For track bike, you dont need that steering angle at all. It isnt trying to back into a parking spot at walmart. And a lot of times the swap to the big fork swap is the cheapest easiest way to get what you need out on the track. Ive ridden them on the street a bunch too. No real complaints. We are not drifting these things, steering angle isnt a huge need.you need to know how much steering lock you might loose when fatter fork tubes bump the frame, like this bike with 929 forks that is an unrideable showbike and won't steer more than 15 degrees left or right of center.

Some are just done for the look, a applaud that too. Hawks look stout with the big forks. I wont shit on a front end choice any more than i will on a paint job. If you think it looks cool, it looks cool.Don't spend money and buy, spend time and learn.Comment

You def have to keep it in mind for parking lot maneuvers after coming from other bikes. My modest RC26 front conversion will catch you out when you dip that thing in for a low speed turn and you run out of steering lock. Had to do some very quick foot dabs a couple times."I couldn't afford NOT to buy it!"Comment

STUPID QUESTION OF THE DAY: Why must all (yes, all, no matter what style or brand of bike, sport bike, adventure, all) USD forks be anodized gold?

Well, I’m glad you asked that question young man! And it is quite evident you’re wiser than your years! It’s obvious that you’re asking is for the benefit of the rest of the crew, as they are too timid to ask ... Okay, here goes ...
The CBR600RR forks on my Hawk as shown, are indeed “golden” I believe the USD forks from introduction up to 2006, then in 2007 they were black!
In the evolution of that model, Honda’s genius engineers determined the reduction of aerodynamic drag from the gold to black color change plus the resultant weight reduction (everybody knows gold is really heavy, right?) was enough of a performance advantage to put it at the top of the highly competitive 600 class. An added advantage was the black absorbed more ambient sunlight thusly “pre-warming” the fork oil for optimal performance.

Well shit. I just "scored a complete 929 front end for $100. Making me have second thoughts
