Whilst Sushi is considered a fast food delicacy in Japan, the Yamaha SR400 is one of the most favored custom bases for Japanese motorbike builders.

On our quest to invade the Japanese custom scene we have encountered a long list of custom shops crafting and worshiping the Yamaha SR400. One of them is Motor Rock who we have already featured on a number of occasions. When it comes to customizing motorbikes these guys are pushing the boundaries of the custom world. Their portfolio of Custom Yamaha SR400’s is packed full; each build claims a mark of individuality and the true essence of Motor Rock.

Custom Yamaha SR400 MotorRock 6For today’s feature we are taking a look at Motor Rock’s latest build a Custom Yamaha SR400. The base for this custom beauty was a stock SR400, which was stripped down to the frame. The stock frame was heavily modified to adapt the new style. The stock engine was crowned with Motor Rock’s Biller breather filter, a Keihin FCR carburetor fitted with a remolded Gravel Crew long straight muffler.

At the front this custom Yamaha SR400 features Motor Rock’s 69Bar LTD style standard handle bar with switches and chopper style grip. A Bates headlight 5-3/4 inch bolted on Motor Rock’s bottom mount light stay and a POSH small winker.

At the rear the bike features an Easy Riders drilled taillight, vintage step type BSA footpegs and a one-off Razzle Dazzle seat. The fabrication work on this beauty includes a remolded Bonneville fuel tank, 69Box battery case and a remolded XL rear fender. Other parts from Motor Rock’s catalog includes a side number kit Type3, a drilled sprocket cover and 69Decomp decompression lever.

The finished bike rolls on Motor Rock’s excel wheels wrapped in SP MKII Avon tire at the front and SM MKⅡ Avon tire at the rear. All the elements on this custom Yamaha SR400 have been put together with fine precision. The navy blue metallic colors with white stripes and the Razzle Dazzle seat adds a vintage feel to this custom beauty.
