Offset Front Sprocket - Alexander_V - 23-08-24
Hello Guys,
I am struggling to find a dealer or a manufacturer of offset front sprockets. I need one (10 mm offset) for my project that I am modding my fazer 600 with a slightly wider swing arm and I just cannot seem to find anywhere I can order one these days.
I have emailed some folks in Spain and Japan... but no answers yet.
Could someone please let me know how/ where can I get one ?
Is there someone who can manufacture this and ship it to me?
If I have someone cut and weld 2 sprockets so they fit my needs what do I have to have in mind, is it strurdy enough if it is well welded?
If someone knows which other motorcycles have the same standard of sprocket attacment (the hole in the middle of the sprocket) pleas share so I can have a broader range to search with.
Thanks a lot in advance for any notes, thoughts, links and recommendations.
Best Regards
Alex

How about getting a machine shop to weld two together then lathe away the inner bits on the outer sprocket and the outer bits on the inner one?

The Old Suzuki GS1000/750 used to have one, but dont know if the splines would be the same. Some came with a standard sprocket and a spacer

It did cross my mind, but I was wondering if welding the sprocket was a good idea altogether, because of forces applied to it. Would you say that if it is properly welded it is no issue for concern?

These are not cheap £100 and it’s Germany, and you will have to cross match fitment. EBay item 325256647204 . Wanted one for my 350ypvs hybrid , but not now needed. Surely welding would be ok as long as kept square, though unless it’s done yourself or mates rates the price would be up there in any case.

Also i think NK racing here might do what you are after, again not cheap. Ebay item number is not for fzs600 , but it guides you to sellers site and you will have to go through their other listings to match your bike spline size. Can help to find part numbers amongst other sellers that crossmatch other models, perhaps even makes. Just takes some trawling, or contact b&c and supersprox ? If i have that right.

Well as i now have a small MiG welder i think I will just slap a tac on when looking at this

In my experience these sprockets are hardened steel. Incredible forces are transmitted from the splines to the teeth. Cutting this material on a lathe is extremely difficult, welding it will result in cracking. The only proper method what I can think of, is annealing it to reduce hardness, machining/welding it and then heat treating it to proper hardness again. Without knowing the exact alloy it's not gonna be easy... let alone to find a machine shop who will do this for you, and then there's the cost.

Good point
Ok make sure its the revised full depth nut and use thread lock then?
What abut using a centre punch on the gap between the thread and nut to deform the thread slightly?
other idea use the original 9mm nut and machine up a second one to work as a lock nut?
