First things first, straight pipes don’t belong on a two-stroke. The Wrenchmonkees built this custom Yamaha RD400 not to be ridden, but to decorate a night club in their native Copenhagen, which likely explains choosing pipes that complement the bike’s straight lines over, you know, flowing gasses in an optimal manner. Having said all that, this build emphasizes how simple creating a kick ass cafe racer can be; everything’s more or less stock aside for those pipes, the tailpiece, tires, rearsets, bars and front numberboard/headlight. The ‘Monkees have essentially just tidied things up, gotten rid of what’s unnecessary and applied a simple paint job. But, the results are transformative; a crappy ’70s bike suddenly looks more futuristic than anything released in 2010. You could probably do the same thing yourself.
