Quality Optibelt product. 11.3mm x 912mm V-belt.

Don’t get stranded – carry a spare!
Aircooled engines rely on this belt to drive the generator and, in turn, the cooling fan. A snapped belt will quickly result in a very hot engine. A slipping belt will also result in reduced cooling. Be prepared: for just £5, this ‘insurance’ offers a very good deal!

    Faultless service - as always from J.K. Product was as described and received very quickly.

  • Doh!

    Converted my dynamo to alternator. Noticed that I had a LOT of particulate building up around the fanbelt area. Then realised I was slowly eating the belt. Turns out that alternators require this size of belt which is slightly longer/wider. All good now.
