Hahahaha, how could it be weak/fail when it spends so-much time in the air? I do know
BMW had a cast front wheel problem that got warrantied, by replacement with a 'new, improved' design. It was their Airhead series motorcycle 'snowflake' wheel design, when it was first released.
The first two years VMax used the design of wheel first popularized by the inventor of the spoked, cast-aluminum wheel, a company named Lester. They were 'all the rage' back in the 1970's. Because of their design and engineering, Kawasaki bought the rights to the wheel, and their transverse inline 4 motorcycles used them extensively. Even the lesser bikes used them, as a 'premium' design.

When H-D released the Sturgis, with its belt-drive final drive and cast aluminum wheels, Kawasaki at the same time released the KZ440D1 belt final drive with its cast aluminum wheels, and one-up in the Sturgis, the Kawasaki had six-speeds, and a counterbalanced engine. The bike wasn't as-popular as their LTD but it was a different take on a mid-displacement motorcycle. Occasionally the KZ440D1 gas tank design shows up on someone's custom motorcycle. It's quite handsome. The LTD uses a different gas tank design, a more-traditional 'teardrop' design.
Lester-style wheels on an '81 Sturgis. Note the number of spokes, nine.
Probably one of the best-looking bikes ever from Milwaukee. H-D would use belt primary drive and belt final drive, both having been used by the H-D aftermarket.
An '82 KZ440G1 I once owned, I bought it non-running, from the original owner, who was moving back to Missouri from FL and didn't have space nor the means to carry the bike back with him. It had a decal from the Missouri dealer on the rear fender, a complete toolkit, the last registration, and the owner's manual. The bike had compression and spark, the manual advance was broken and needed to be replaced, my machinist had a bucket of 'em from various Kawasaki's he'd worked upon, he said, "they all use the same one." Well,
good! I cleaned the carbs and got a new air filter, lubricated the control cables, replaced the front brake fluid, checked all the lights, and gave it to a friend for sale at his shop, it soon went to a hipster on Miami Beach, who had an accident with it after a couple of months, he wasn't seriously hurt. You have to dodge all those Ferraris, Lamborghinis and McLarens running around South Beach.
Note the number of spokes, seven. Aesthetically, an
odd number of spokes is perceived to be more-attractive than an even number of spokes.
