Ribbed Aluminum Fenders

ribbedfenderPersonally, I love aluminum body work in either form, raw, wirebrushed, mirror polished, anodized, partially painted. Not only because it’s a noble and beautiful material that will never rust but also because it will make your bike much lighter. There are a few available bolt-on gas tanks and fenders on the after-market scene, but sometimes the issue you may have is the strength of the welds and thickness of the aluminum used.

And the sad thruth is that some of these parts may not hold up to vibrations and road abuse. For fenders a good address is 7 Metal West. Dan Knoblauch handmake them starting from a .125” thick aluminum sheet where many competitors use only .050”. They are 1-piece fabrication and when formed there is no weld seam to sand and fill. They weight about half the weight of a comparable .090″ thick steel fender and help you save 2 to 3 lbs. These ribbed fenders are offered in 5″ wide, 37″ in length, 26″ in diameter for a 16″ wheel and 27″ in diameter for a 18” wheel. Starting at $140.00. Call Dan on my behalf at 414.477.0380 or visit 7 Metal West.

    Aluminum fenders need rubber isolation inserts inside the fender holes, or the vibrations will hog-out the holes in the fender.

    You are taking your chances with aluminum fenders and gas tanks, just ask Don at fat kats. I could only imagine how many tanks came back for cracks and leaks.The vibration on the bikes WILL find a week spot till it cracks. When you spend money on parts, saving a couple of pounds is not worth the price of replacing, or PAYING for PAINT a second time. How many painters do you know will repaint your second tank or fender for free? Painters know that aluminum brakes. They like repeat work because they get paid a second time. Pay once or keep paying over and over. But hey, your bike is two pounds lighter.

    It’s all about how you mount them.

    I agree, it’s all how you mount it. I mounted an aluminum gas tank to a friend’s bike 10 years ago, we used rubber grommets and seals where necessary and the tank has never cracked or broken. Do it right the first time and it will work.

    “…vibration on the bikes WILL find a week spot…”

    Count on it……. probably the major cause of gas tank leaks.
    And ALL motorcycles vibrate (yes, even Beemers)……. 🙁

    But that’s why God made old tire tubes.
    Cut your own rubber shims or get composite & rubber washers at the local hardware store.
    Don’t they teach that in shop class anymore…???
