Front fender too short?

by Steve #001, 11/01/99

Dirt and grime all over the place? Adventure Motorcycle Gear has the "Extenda-Fenda". These 5 inch extensions a about $30. Made of black plastic, with a matte finish, they fit nicely the contour of the stock fender. The unit looks sharp on the bike and offers protection from all the "road gunk." The extension is held in place with adhesive tape so that small holes may be drilled to secure the piece to the stock fender with small screws. The sheet metal screws provided with the unit should be discarded. Instead, use three flat-headed machine thread screws with locking nuts or acorn nuts to the outside. After securing the extension in proper position with adhesive backing, mark carefully to drill three holes. One should be centred and the other two off to each side. Be sure the fender is removed to do all this. A good idea is to seal the underside seam with silicone sealant to keep road gunk from seeping through. Go slowly in all of this, plan, measure, and double check. See the photos for finished looked. Adventure Motorcycle Gear is in the classifieds.

"I was just checking an extender out for my 97 F650. Here's the reply I got to my e-mail: "We carry a front fender extender st $29.95, but no yoke protector for that model. Shipping is $4.00."

Fender Modification to fit a 21" Inch Wheel

Kevin #419, November '01

I carved out the front fairing to obtain sufficient clearance to mount a fender to the bottom of the triple clamp bracket in those four threaded holes that reside therein. Also, I added an arc fork brace.

Such a fender modification is required if you are to fit a 21 inch wheel to the F. I bought a BMW front wheel hub and had some local guy build a wheel around it. $200 for the hub and $300 for labor and spokes/rim. If only the price of the tkc bothers you, its more cost effective to keep replacing the tires at 3,000. However, a 21 tire gives a better ride in bad terrain and the high fender prevents mud from collecting under the fender where the front wheel may become immobilized.

Acerbis Fender

Mike #789, December '01

Here's a view of my bike with the (Higher than Stock) Acerbis Fender. So far I have had no problems with debris hitting the radiator.

The fender reaches just below the top of the plastic bash plate. Here's a view of the Bracket.

I installed an Acerbis Baja front fender on my '97 about 13K miles back. It stops the mud and sand and allows cooling air to the radiator. You'll need to remove the "fork brace/fender support" to install a 21" tire, I believe. Ike647

Wunderlich Fender

"I used the excellent (and expensive) Wunderlich fender mount and mounted a Acerbis 'NOST' fender on my '99. (Same as Baja without vents) Didn't work in Vegas during the summer. Even with many vents cut in the fan stayed on almost continually. I'm about to put it back on for the winter as the temp is down to 70°-80° now. Don't see why the Wunderlich bit wouldn't work on a '97, but use the Baja. (I didn't cause it only comes in white)." David#476
