Classic Bike (UK) - - World -

I was sur­prised when I opened my Fe­bru­ary 2016 is­sue of Clas­sic Bike and saw the ar­ti­cle on the Bavar­ian Boomer – the BMW Racer by UMC. I had just taken de­liv­ery of a wellused 1978 BMW R80/7 with the plan to build it into a café racer. The ar­ti­cle pro­vided ex­actly the re­as­sur­ance I needed to set me on my way, and my bike was fin­ished just over a year later. My ob­jec­tive was to re­tain many of the BMW de­sign fea­tures but in­clude new com­po­nents to give it a touch of racer-tech. Us­ing pho­tos of sim­i­lar bikes and tak­ing in­spi­ra­tion from your sis­ter mag­a­zine Built and the Bike Shed CC shows led me to fab­ri­cate my own rear sub­frame, Tig-welded from CDS tube. Af­ter dis­cussing spring rates and ride heights with Hagon I fit­ted a pair of their ex­cel­lent shocks. The bike came with a very deep petrol tank and in­cluded an in­te­gral tool­box which now houses the fuse panel. A high ca­pac­ity bat­tery is lo­cated un­der the gear­box. Paint was by Bernie’s Cus­tom Stu­dio in Dorset (they matched the colour to that of a friend’s Honda Civic). The en­gine came with very good com­pres­sion and oil pres­sure and only re­quired a top-end re­build, with stain­less steel pushrod tubes added. Cylin­ders, heads and wheel hubs were vapour blasted and the wheels re­built onto the orig­i­nal al­loy rims with stain­less steel spokes. I fab­ri­cated the ex­haust head­ers out of stain­less steel and fit­ted Me­ga­ton-style si­lencers, which look and sound great. Tarozzi rearsets and ad­justable clip-ons, plus mod­ern Kawasaki switchgear and a Koso mul­ti­func­tion dig­i­tal speedo/tachome­ter fin­ish it all off. My only re­gret is I’ll shortly have to sell it on, as my pas­sion is re­ally in the build. I al­ready have the urge to get on with my next project. GARETH PEM­BER­TON
