This throttle aid - 99p.
Laser thermometer - £8. Great for checking exhaust temperatures to ensure even running.
and the big one. Adjustable handle bar. - under £30 !!!! The engineering is a bit Isambard Kingdom Brunel but it's amazingly well made and makes ordinary bars from Renthal and the like look hugely overpriced.
and those were the delivered from China prices too !!
