i want to lower the front end 3.5" has anyone ever put a sportbike front end on a 750? or anyone know of a bike that has fork legs that are shorter but same diameter? i can lower the fork by moding the internals but 3.5" is a tall order and prob wouldnt leave me with much travel. maybe lower it 2.25 and let it stick up 1.25 above the top clamp?

what size head bearings do these bikes use? 25x47x15 and 28x52x16.5?

I dont have any answers for you but I too would like to know if anyone has done any custom work to their front end. I want to put a springer on mine. just not sure what to buy.

Why would you want to?

I am going to assume you plan on lowering the rear at least 4 inches too. ...otherwise your going to f-up the bikes handling and likely hurt yourself.

But then again, why?

yes the rear will be lowered as well. i want a bit steeper headtube angle... i am an experienced sportbike rider and the sensitive handling will not be a problem, it will not be steepened enough to cause high speed wobble tho.

as far as why, because for a big 750 like this, the forks are thin and dinky.

Cool...and I agree.

I thought there was a post somewhere about replacing the steering head bearings with tapered roller bearings...but I can't find it. (That be the way to go)

unfortunatly the next quest you will have for me is how long are the forks for this... the answer is I don't know. But I do have the Fork tube Diameters, so you might be able to dig in a little bit further and find some fork tubes that match the length you need and if you do find this info out, please pass it my way because I have been searching every where for several years with out any luck.

Here is the tube list

Lotsa Info

I admire initiative and determination, but reinventing the wheel just ain't necessary. The most comprehensive list of fork specs I know of is in a little pc of work titled "The Jap Bike Bible". For a list of HUNDREDS of specs, including other important details like axle size, bearings, neck sizes and such, try this link
http://www.clubchopper.com/forums/me...diameters.html.

Naturally, the one missing pc of info is the overall length.

I can tell you from my own front end conversion that the forks from a FZ600 are a slip in operation, give you much better valving and the handling is unreal compared to stock. You'll need a new 600 fender and the fender mount is actually a fork brace on the FZ so it's a double win-win. As the axle center is directly under the tube center, the rake remains the same but you eliminate 1.375 (one and three eigths) of trail, putting you at 3.65 inches trail and 32 degrees rake. The bike remains rock solid at speed, but the low speed handling (that wallowy fall over and wander sensation) is totally gone. Also, the slow high speed feel (loved by H-D guys, hated by MOTORCYCLE riders) is gone. Think about it and it turns, No more frame wobble crossing centerlines and bridge grates (tried on stock Dunlops, a Shinko front and a Pirelli front with a darkside Kuhmo rear<<an awesome x 2 combo)!)

And now to add to your list, I'll add that measuring other bikes in my garage. All measurements are wheel off the ground (fork extended) and from top of tube (not including any caps or pressure fittings) and fro tube top to axle centerline.

1975 Kaw Z1 = 30.375 inches long
2001 H-d Sportster xl1200 = 30.5
1986 VN750 = 33.5
2008 Yam VMax = 34

P.S., I finished the 34 to 36 mm carb mod and the digital NO2 addition to my "stock" VN750 as mentioned waaaay back as a project in the works. Showing 77 Hp @ 8200 on gas and 92 on the juice @ 9200. And the engine is holding up just fine, thank you!

i want to lower the front end 3.5" has anyone ever put a sportbike front end on a 750? or anyone know of a bike that has fork legs that are shorter but same diameter? i can lower the fork by moding the internals but 3.5" is a tall order and prob wouldnt leave me with much travel. maybe lower it 2.25 and let it stick up 1.25 above the top clamp?

what size head bearings do these bikes use? 25x47x15 and 28x52x16.5?
i put a front end from sport bike this winter lowerd the back 3.5 inch seat hight is at 55cm
