British motorcycle accessories manufacturer Renthal has issued a voluntary recall of its Gen 1 and Gen 2 clip-on handlebars, due to a risk of the aluminium alloy material developing stress corrosion cracking and potentially failing.
Of the 10,000-plus units sold across the world – 5,000 of which were in the UK – 22 are said to have so far failed, with no reported injuries.
According to Renthal, the specific material used in the manufacturing of these clip-ons can be subject to stress corrosion cracking when under the ‘simultaneous influence of mechanical “tensile” stresses and an aggressively corrosive environment.’
Riders using the clip-ons are asked to stop riding immediately and return the hardware to the company for a free replacement set. While only the clamp is affected, the tube also needs to be returned. Riders will receive a free set of grips with the new clip-ons.
Photographs and details on the Renthal website help to identify the different clip-ons, and an online form allows riders to arrange the free return of the recalled items. Providing the company has received these, shipping of the replacement units will begin on September 7.
