‘85 Yamaha SR400 – Addiction Customs

With a hot sun beating down, 45 degree Celsius heat just outside my front door, last week my thoughts drifted to the beach and how nice it would be to live near the ocean. Cool breezes, the sound of waves and a sweet ride to experience it all on. Then this bike appeared in my email inbox. Must be a sign. A sweet thumper, built with the surf in mind, this 1985 SR400 has been made over to suit the beach bum lifestyle. With a build brief that appeals to both form and function, this is definitely a bike I would be happy to ride on a sunny day. Or any other day for that matter.

The crew at Addiction Customs had a great base to build from with the SR. Having imported the bike themselves, they knew the condition of the bike at the start of the build which allowed for the perspective to be put on reworking rather than rebuilding the machine. Another bonus was the owner being in no rush to pick up the SR, with the thumper staying at the AC workshop while its owner took a surfing holiday.

The build brief was simple, the bike needed to be able to carry a surfboard and/or a passenger, based around a matte black paint scheme,  and no Firestones. With this in mind, the bike was stripped back to a bare frame.  Whilst the Yamaha was naked,  the factory rear hoop was removed and an in-house upswept loop grafted onto the frame. Once the custom hoop was on, the builders assessed the mounting points for the surfboard rack. It was decided the surf rack would need to be ‘easily removed, wouldn’t compromise the look of the build and be stealthy in design’. To achieve this,  the Internet was scoured for existing bike racks that could modified to suit the aesthetic of the bike. 6mm plates were welded to the front frame gusset, while at the rear an underslung mount was fabricated and fitted up.

Once the rack was mounted, the seat pan, fender and indicator mounts were fabricated to suit, and the rest of the frame detabbed. After ensuring everything fitted, it was off to the sandblaster to prepare for the thumper’s new paintjob. The pristine tank and stainless rear fender were sent to Smith Concepts, the result a simple matte black base emblazoned with the Yamaha logo, detailed in variegated gold leaf and finished with a white pinstripe. Addiction Customs are happy with the finish, describing it as ‘clean and classy’.

Once the tank guard were finished, the remaining frame componentry was cleaned up and powdercoated. Frame, swing arm, wheels and hubs all received the powdercoat treatment,  giving the dark aesthetic the owner wanted in their ride. To round out the dark side of the build, the engine was prettied up and given a coat of matte black paint. Happy with the SR powerplant itself, there are a few mods that lens themselves to performance. A Keihin CR38 roundslide carb had been fitted, along with a K & N pod and breather. To offset all that black, a stainless reverse cone muffler was polished up and mounted. In addition to this, bling was added in the form of gold engine bolts, sprockets and drive chain.

From such a simple build brief, Addiction Customs has managed to build a sweet ride. In-house fabrication, and ample time to create the look they wanted, means that the owner of this Yamaha has one of the coolest rides parked up in the beach car park, or anywhere else for that matter.

Postscript from Nick at Addiction Customs:

“A couple of corrections if I may; after looking at all the surf racks on the internet we didn’t like anything out there, so the surf rack was completely hand fabricated, hand bent alloy, we even made the bungees from shock cord and clips, nothing off-the-shelf here. Also, the exhaust was welded up by us, not an off the shelf bolt-on, and the tank detail is all variegated gold leaf. Cheers!”

    Wow, very nice build indeed but the detail on the deposit tank is just astonishing!!
    I wouldn’t be surprised if we see plenty of builders using that idea, amazing idea

      Thanks @algonz:disqus!

    Thanks Pipeburn!

    Very nice bike, it’s a shame that all the nice paint on the front of the frame and on the engine will be ruined for lack of a front fender, as it gets blasted by sand coming off the front wheel. Maybe it win’t be ridden much.

    • Nick

      Customer didn’t want a fender @MayDayMoto:disqus and did over 500 kms in the first week. No sandblasting evidence so far, though he has decided he might like a front fender to avoid interest from the police, as we live in a nanny state here in Australia! The bike wasn’t built to ride ON the beach, just to it. We are awfully civilised here and many of the 10,000 + beaches in Australia do have carparks, but point taken and I suspect the owner may add a front fender in the new year…… when he gets back from his latest surfing trip overseas 🙂

      • MayDayMoto

        lol I’m talking about five years from now, thank god the paint didn’t start eroding in only 500km! Belive me, I’m familiar with how a coastline works. In my expericence sand and salt doesn’t stop neatly by the side of the road when you leave the beach.

    You guys need to tell your photographer to take better pictures. I’m not saying that the cool/artsy/magazinesque pictures are bad or that you should get rid of them, but you should have closeup pictures as well. There are plenty of aspects of the bikes in all of your articles that you cover, but don’t show any detailed pictures of. I for one would like to see more technical photos in addition to the “beauty photos”.

    • Nick

      You might like to send that general feedback to the admins of Pipeburn, @Ben, especially as Pat Stevenson was shooting for Addiction Customs. If you are interested in knowing more about specific details on this bike, shoot me an email to info@addictioncustoms.com.au and I’ll see if I can help, Cheers Nick

        I take that to mean that you guys are not the ones to take the pictures? Its not just this bike, all of them seem to be this way, but this one for example has custom made brackets/frame things and a custom surfboard rack, but no good pictures of any of that. Only pictures at a 72.3 degree angle at 94 percent light from 2.389 meters away and a cool background. Yeah, thats cool and all, but I’m not buying the thing, I just want to see the details and the work put into it. Its across the board, not just this article though…

      Cheers 🙂

    • Bowds

      Yep, already had a few 40*c plus days. It’s going to be a hot one.
