Earlier Signature builds reminiscent of PBM’s CX500 café racer and Sportster scrambler had a markedly trendy edge, however with this ’73 Yamaha XS650 — a former racer — Tom went for a way more traditional look, really feel, and using expertise:

The design temporary referred to as for an XS650 café racer that would do triple responsibility as a present bike, road bike, and even deal with the odd observe day — fairly the problem certainly. What’s extra, Tom was striving for a traditional, enduring design that would stand the take a look at of time:

“I labored at making a timeless piece that will really feel at residence for a rider younger or outdated. One thing that individuals throughout a household’s generations might be enamoured with.”

The donor XS nonetheless had some neat period-correct bits from its outdated observe days, reminiscent of an unique tank with flip-up gasoline filler and Marzocchi rear shocks, which Tom made certain to retain:

“There are classic piggyback items that had been hydroblasted, rebuilt, and internally customised to carry out just a little extra like a contemporary shock whereas holding that lovely traditional racer styling.”

The bike is now rolling on 18” Borrani rims laced to the unique rear drum hub and a quad main shoe 230mm Robinson entrance drum, accomplished with 38mm Ceriani forks and {custom} yokes. However there’s than meets the attention with the entrance drum — it’s really a hydraulic setup!

“The entrance forks are the disc brake mannequin, which allowed me to have the mounting factors I wanted for essentially the most thrilling concept I had for the challenge. Up to now I’ve been left underwhelmed by the efficiency of cable-operated drum brakes. To handle this I needed to construct a hydraulic drum arrange, however preserve the standard look of the Robinson drum.”

Tom fabricated a pair of brackets / covers that home the hydraulic actuators behind the forks, and the bike can be operating a hydraulic clutch conversion utilizing a Ducati GT1000 slave cylinder.

The exhaust is a 2:1:2 system constructed in-house from 316 stainless, with an X-pipe below the engine and twin PBM torpedo mufflers.

“All polished to perfection earlier than getting a clear and warmth cycle to make sure a pleasant straw gold color.”

The bodywork is one other spotlight of the construct. The tail piece and bikini fairing had been each created in-house, with a custom-mounted PBM 4.5” Headlight and a refined PBM Delta brand ghosted into the paint.

A set of vertically-stacked Velona Gauges had been mounted contained in the fairing, and the bars characteristic PBM switches, {custom} press-fit bar ends, wrapped leather-based grips, Domino Basic racer throttle, and Accossato levers.

Tom says the using expertise is excellent for a well-sorted classic twin:

“The torquey energy supply proper via the rev vary means it’s enjoyable wherever. The thumping of the engine via the 2-1 exhaust is simply one thing you don’t hear on trendy bikes…The visceral rattle and vibration from the 1973 Yamaha nearly makes you are feeling such as you’re using in black and white.”

Tom says the bike is one among his private favorites, and it lit a hearth inside him for extra traditional classic builds of this caliber:

“I really feel like we’ve walked new floor as a {custom} store right here and I’m actually eager to discover this facet of issues extra. Constructing one thing nearly 50 years outdated and having it cease individuals of their tracks once they see it. The painful quantity of element on this construct permits anybody with a heartbeat to understand the craft…”

In our opinion, “Chrome Canine” blends the timeless attraction of a stainless dive watch with the racy fringe of a classic racer — we like it, and we will’t wait to see what comes from PBM in ’23.
