Let's hope other manufacturers take a look at this and we get more such bikes being manufactured here!

It's a great step and if sales increase Suzuki could start manufacturing the Gixxer here as well.

Re: How the Suzuki Hayabusa is Made -- well, assembled in INDIA

Why is a hyper sport legend like this having an ugly welding line in the swingarm?😕 This ain't a KTM now is it.

Re: How the Suzuki Hayabusa is Made -- well, assembled in INDIA

Do you believe welding makes the part weaker?
There may be inconsistencies in manual welding, but if the welding is a robotic one, then its accurate upto a reasonable standard (like the KTM Duke and RC frame, by the way).

Moreover, unless the technology used is "forging" the metal itself(its an expensive technique), mostly every component is made out of casting molten iron, and welding is a small time implementation of roughly the same thing, so its not reasonably expected to be weaker than other casted components. Correct me if I'm wrong though.


I will however admit that in close up pics, it does appear to be a sore sight, specially on a premium bike. That I'll agree with.

Re: How the Suzuki Hayabusa is Made -- well, assembled in INDIA

Yes it looks bad, but if you see carefully, it's welded at the point just near the axle bolts are placed, rear tyre bolts I mean, and welding that little part does reduce strength significantly, they could have easily made the swingarm a 3 piece welded module instead of this 5 piece one. Forging is costly, but then again it's way heavier than a hollow swingarm like in the bandits and katanas.

While looking at it in such powerpoint way its hard for me to dismiss it simply as a quarter mile shooter as 'Others' tell me.

Re: How the Suzuki Hayabusa is Made -- well, assembled in INDIA

No manufacturer forges swingarms.
They are cast to near perfection and then heat treated and then machined to required dimensions OR they are built by welding heat treated metal bars into desired shape.

That weld you see there is where the swingarm brace(upper section) meets the actual swingarm. The upper part on either side acts as a support to the actual swingarm and hence its called the brace. If the brace is above the swingarm it is an Overbrace. If its under, its an Underbrace.
First gen Suzuki GSXR had an underbrace and then they switched to overbrace.

Even MotoGP spec bikes have weld lines on their brace joints.

Re: How the Suzuki Hayabusa is Made -- well, assembled in INDIA

I don't have much exposure to Hayabusa, but that welded part (above the swingarm), it doesn't appear to serve a significant purpose, does it? I mean, it just holds the mud guard for monoshock, right? If there's hardly much burden on that part, then it seems ok.

Another thing I noticed, there are faint welding signs on the swingarm itself, just beside the rear wheel axle... Now, that is the more crucial spot I believe.


But, I just checked the international websites, and YES, the Hayabusa does seem to have the same welded part in bikes sold in US/ EU. So, it would only be natural to expect the same thing in India. After all, we can't expect Indian employees to change the blueprint of the manufacturing process, or its parts itself.

So, I don't believe there's any concrete reason to be concerned.. The company personnel must have thought about and tested each aspect.

How it looks is another matter though.
