Best purchase I've ever made from a second-hand parts dealer in over 45 years of motorcycling!
I needed a replacement swinging arm for my Suzuki GW 250 as the old one was rusting badly inside and found one on Boonstra via Google for about £25 + shipping to the UK from The Netherlands, which came to about £70.
It arrived only 4 days after ordering and upon opening the box I was astonished to find a near mint swinging arm complete with both spindles and chain adjusters. Apart from one small 10mm scratch the whole thing looked like it had been taken from a BRAND NEW bike! To put this into perspective, the other rare examples I'd looked at from UK and German breakers were tatty and well used (One was even listed as fire damaged) and didn't include the adjusters or spindles. They would have cost from around £60 to £150 with shipping for just the bare arm!
I'm very, VERY happy with my purchase and would absolutely recommend Boonstra to anyone based on my personal experience. Thanks for the brilliant service guys!
