Retro cus­toms

Xsr700-based Apex Ruler is the lat­est star of Yamaha’s Yard­built scheme

Motorcycle News (UK) - - This Week In Mcn -

Just when you thought Yamaha had eased off the throt­tle on their Yard­built pro­gramme, an­other ab­so­lute stormer is un­veiled. The Apex Ruler, built by Walzw­erk Rac­ing in Ger­many, is 50% café racer, 50% street tracker – and 100% awe­some.

The Apex Ruler started off life as an XSR700 but only the en­gine, frame and petrol tank re­main. In stan­dard trim the 700cc par­al­lel-twin en­gine in the XSR puts out 74bhp, but the en­gine in the Apex Ruler has been tuned for speed. The most vis­i­ble change is the light­weight Sc-project ex­haust sys­tem, but hid­den in­side the body­work is a DNA Rac­ing air­box and Power Com­man­der. Help­ing to achieve mar­ginal gains is the 520 pitch chain con­ver­sion, while the Pirelli Su­per­corsa tyres are help­ing to get the new­found power to the ground.

To help the chas­sis keep up, the sus­pen­sion has been swapped to Wil­bers front and rear, with new LSL rearsets, han­dle­bars and levers fin­ish­ing the han­dling mods. To help keep down the weight of this wild cre­ation, the wheels have been re­placed with Ro­to­box car­bon items and the all-new body­work is made from 2mm thick alu­minium. This means that the whole build weighs in at just 150kg. Not bad for a retro cus­tom job.

While the tank is orig­i­nal, and per­haps a lit­tle out of place, the paint­work is all new. The red met­alflake paint is by a painter lo­cal to Walk­w­erk, who has hand-painted the speed block pat­tern from the era of two-stroke ter­ror.

We think it looks great but now we want to see the same treat­ment on the more pow­er­ful XSR900, so it’s got a lit­tle bit more go for all that show.
