I have posted pics of the front end earlier in this post. I am still waiting on parts but as soon as i have them there will be a build thread. ;)

So what you are saying Havoc is, as long as I have a new stem made and that will make it so I dont have to finagle with ANYTHING else?? When you put it that way, it doesnt seem so bad as interchanging all these parts, custom parts, different bearings, etc!

Now, as far as the 21" front wheel goes, thats not set it stone, what do you think the biggest I could go with a sportbike front instead of dirt bike?


Ok, so at this point lets say I have the inverted forks on now. What should I do about the wheel, hub, brakes etc? Thats where I'm kind of lost now that I understand the swap part....


Thanks so much

Are we talking stock front wheel?

Or the front wheel designed for the new front end?

Well it depends on what you want ..... need to figure that out first.

If you want stock wheels with aftermarket forks.... that means more fabrication to get everything to fit.

If you want new forks with matching front wheel.... then easy as pie. But remember the rear wheel also.

Start with a list.... then go from there. Attack one thing at a time and before you know it it'll be done.

Anything you need.... I'll help and so will hundreds of others. ;D

I mean I dont HAVE to have a 21" front. I know I DO want to have a nice wire wheel and clean looking brake setup. But at what cost? Do I buy a rim and have it laced up, do I use a matching disk brake setup from maybe the front end swap I use? I guess I just dont know how much it would be to do that, thus a big decision maker. I dont want to have a boat load of money in this thing, I just want a clean looking, simple and effective bike to ride around town every now and then...

The easiest way to go is to use the wheel that comes with the front end and the corresponding one on the back, way easier and more cost effective way to go.
You can have hubs manufactured to suit for a spoked wheel set but it will start getting very expensive very quickly.

Well we've established that you want USD Forks... Check

Wire Wheel... Check

Dual or Single Disc Brakes? Single will be easier.

Ease of fabrication without an astronomical price tag... Check.

I see no problems here...  Looks like it's going to be a Dirt front end more and more.

Start looking at 2-stroke version bikes in the 250+ cc range. Tell me what you see. You like?

Boom.... we are on our way.

Yeah, single disk brake should be fine.

The XZ250 looks alright, but how is it going to ride? Just sounds odd to me to put a dirt bike front on a motorcycle :P

Hi Havoc, what about the hub and axle they will have to be a custom setup to suit the spoked wheel. If i was going to do what you want on a budget i would just put progressive springs in the stock front end and good shocks on the rear and be done with it,much simpler.

Not if he's willing to use the stock wheel for whatever front end he uses. That's the beauty of using the triple clamps with a new stem.... spacing is the same between the forks. The only difference is the spacing vertically around the neck. Especially if you are using dirt forks. Then all you have to do is space out the rear to match.

Now if you want to use the stock HONDA CB wheels.... well that's getting into some serious fab work for just a wheel. Especially if you want to go easy on your wallet.

There are loads of different springs for dirt front ends, beauty is most are fully adjustable (late model ones anyway) and can be used with a wide variety of different valving and such to give you a better ride. I personally have never ridden a street bike with a dirt front end with stock valving and springs. So I'm not sure how it would feel. Probably smooth as a baby's bottom. lol.

And if you cannot find anything for the particular front end you are using, you can always do some spring shortening and use spacers, even on USD forks. (that's a little touch and go though and only recommended for the non faint at heart)

i would keep an eye on this front end. If i were going to do the swap and stay with spokes i would def. go with a dirt bike just to stay away from the mess of fitting a new front wheel.

Check out some factory enduro bikes. Dual sport whatever you wanna call em.

They have different valving stock to help with road chatter and feel. Way different than a pure dirt set-up.

That ebay link is a sweet set-up. From there all you need are stock OEM pieces or any aftermarket piece that is made for that front end. And being a 2000 they shouldn't be hard to find.

Kawasaki makes a great handling dual sport 250. So does Yamaha. They are street legal and have slightly wider front wheels than their dirt only counterparts.

         Listen, take into consideration everything that has been said here and then, check out this link to ohiocaferacers.com and there you will see a Honda CB350 that Greg has fitted a GSXR750 front end on and check it out. Also, check with Greg, as he will guide you in the right direction about his swap. I know that your bike and his are different, but, it will be worth your while to talk with him. And anybody here who knows of his work and expertise, will vouch for that! Not saying ANYTHING about those who have offered advice on this, I just thing that hearing from Greg, will help you make the decision. Good luck on your venture.

                                Take care, Bill ;)  
             
                               http://www.ohiocaferacers.com/  Then go to "Bikes"  Then to the CB350RR


                           Tried to post pictures of his wotk, but can't. Just have to go there and see for yourself. ::)

Ok, I'm still taking suggestions, opinions, etc


Just want to clear up a few things still....


1. Havoc - when you say "space out the rear to match"....what are you meaning? I do know this, I want to hardtail the bike.

2. what are "USD" forks?

3. If I end up with a sportbike front instead of a dirtbike front, whats the biggest wheel I could run without complications? 21" isnt set in stone...


BTW, I def dont want to keep the stock CB wheels!

Oh, and I will check out Greg as well


Thanks everyone

"USD" are upside down forks.  The problem with a sport bike front and a 21 inch wheel is that most if not all sport bikes have a brace where the front guard is mounted to stiffen up the front end, this would restrict the size of wheel that will fit under the brace. A new brace could be made, so i depends once again on how much you want to spend and how much fabrication you want to do.

Read this thread. they are doing what I think you are trying to achieve.   they modded a busa front fork to a cb550 bobber they're building.

http://www.thechopperunderground.com/forum/index.php?showtopic=32232

also the bike the put them on is here.

ive read this thread a few times and it has given me some ideas.
