Custom Motorcycle Builds in Brisbane - Mostyn Performance Motorcycles

For Custom Motorcycle builds in Brisbane look no further than Mostyn Motorcycles. We offer a wide range of work including fabrication, painting , spare parts and tuning all in-house.

We’ve been building custom motorcycles for over 20 years with Harley Davidsons, Thumpers like SR’s and GB’s as well as classic and modern Honda’s etc.

Let’s face it, wiring is very few people’s idea of a good time. In older bikes especially (and when past owners have got trigger happy with pliers) there is usually gremlins that surface. Luckily we specialise in fault finding and rectifying electrical issues.

Our Dyno means that your new custom motorcycle won’t just look good, it’ll go as good or better than new. With only a few dynos in the region and our ability to restore old carburettors our custom motorcycle builds are some of the best and most reliable in Brisbane.

Our fabrication team have had over 30 years of experience combined and we offer TIG and MIG welding. CNC laser cutting and router are also part of what we have to offer. Some of our projects have included custom tanks built from steel and alloy, hard tail conversions, bobber seat alterations and custom exhausts.

“You’re only limited by your imagination!”

CAFE RACERS

Mostyn Wild

This build is one in a series of Braaap Mercury builds we are doing.

The 'Wild' includes:

Whitewall tyres
Custom paint
Airbox removal
Custom seat
Different handlebars/graip and mirrors
price: $7000.00

Mostyn Envy

The Mostyn Envy is one of our favourite Cafe Racer builds to date. The call was for a british racing green 'but in metallic'. The chocolate diamond stitch seat works really well with the colour.

The upgraded carb meant we were able to clean out the space where the airbox would have been and get another 10% performance out of the bike. Small touched like the headlight grill, bars and mirrors just finish it off.

Price:$4900.00

CB550/4

This CB550/4 started off life as a quazi bobber with questionable characteristics. What we ended up with is a light and growly machine that had no troubles in the twisties and looks great standing still.

BOBBERS

SR500

This is an SR500 that has been chopped at the back. Unlike a lot of our bobbers, this one kept some rear suspension for a slightly easier ride. Very low and very loud. An absolute pleasure to ride.

Jailbird CX500

The jailbird started life out as a late model CX500. We dropped the back and made custom fenders up. We also changed all the lights to our 'slotted' range. the airbox was removed and airpods installed. The 2 into 1 exhaust was ceramic coated and the custom seat was made in-house to get that low profilefeeling. in total we removed 30kg's off the CX and the satin black paint job finished it off.

XS650 Hardtail

This is how a lot our XS650/Triumph builds start. this jig allows us to get the frames millimetre perfect. From here we mock up the build before pull down and final paints etc. Notice the ability to extend/shorten the back end as well as change the head angle.
