Technischer Überwachungsverein (Technical Inspection Association, or TüV) in Germany is an independent laboratory that tests the fatigue strength, manufacturing quality, and fitment for a wide range of consumer products, with special emphasis on automotive and motorcycle components and accessories. Biltwell handlebars and risers that have received TüV verification are among the strongest and most thoroughly well-tested motorcycle parts in the world.
We don’t knurl our bars because doing so reduces the surface area where the handlebar makes contact with the risers, thereby compromising clamping power. Stock and aftermarket steel risers commonly found on cruisers and custom big twins have a material density 4 times greater than aluminum. This density doesn't let knurling bite into the riser material, which in turn compromises clamping strength.
