Testimonial from Guy Owen in New Zealand, February 2014:

“Just reporting back regarding those 7mm stem valves, titanium collets and spring retainers I bought from you last year.

Since fitting them the Venom has covered 10,000 miles without messing around too much speed wise with plenty of winding hill work etc.

Am very pleased with the performance which is still up there.

Please find attached a copy of the local ‘Nelson Classic Motorcycle Club’ paper which features the Velo on the front cover”...
