Objective Constructed Moto is not any one-trick pony. The Australian workshop is up for something, with a portfolio that boasts all kinds of manufacturers and {custom} construct kinds. Even so, they raised a uncertain eyebrow when the temporary for this tradition Yamaha Virago landed of their inbox.
“I wasn’t positive if we’d tackle this construct,” says the workshop’s founder, Tom Gilroy. “The XV750 isn’t certainly one of my favourite bikes to work on, that’s no secret. I discover them over-saturated within the {custom} world, and sometimes undercooked.”
Ultimately, the passion of his shopper received Tom over. Fingers have been shaken, and the bike was delivered to Objective Constructed Moto’s Gold Coast store with a field of additional components.
“He was passionate and tremendous eager to have a purpose-built machine, and had his coronary heart set on his 1981 Yamaha XV750 Virago Midnight Particular,” Tom provides. “He’d already began sourcing components and doing a number of modifications. From this, I may inform he wished the job completed correctly.”
The bike got here to PBM with a Yamaha R1 entrance finish, Cognito Moto yokes, and the rear wheel from a distinct mannequin Yamaha XV. The mission’s targets shortly grew to become clear; higher efficiency and dealing with, and a pointy and fashionable disposition. An aggressive under-tail exhaust was additionally on the wishlist.
Tom’s notes additionally included one very particular job; “repair that ugly swingarm.” So the PBM crew ditched the square-tubed OEM swingarm and welded up a fetching trellised chromoly unit as an alternative. A {custom} rear shock from Experience Dynamics props up the rear finish.
Additional care was taken to tweak the bike’s experience peak, together with some deft engineering to elongate the entrance forks. “Straight-swapping the XV750’s forks for the R1’s makes it far too low,” explains Tom. “It seems to be nice, however one pace bump somewhat too fast and also you’re left with a complete loss oil system—no bueno.”
Subsequent, PBM tackled the subframe and wild exhaust system multi functional go, biking between numerous areas of the bike to verify every thing match collectively completely. It quickly grew to become obvious that the rear engine mount was going to be in the best way of the rear cylinder’s exhaust header, so Tom and his crew hollowed out and re-braced that part of the body.
The stainless-steel headers now snake their approach across the engine and up via the tubular subframe, exiting in a pair of burly field mufflers. An abbreviated saddle is perched on prime, with the license plate and taillights now hosted decrease down, on a custom-made bracket. how properly every half enhances the following, all that effort was value it.
Subsequent, PBM turned their consideration to the XV750’s engine. Or reasonably, their comparatively new engine-building division, Objective Constructed Efficiency, did.
In went new high-compression pistons, upgraded conrods, and greater valves. The crew additionally rerouted the consumption from the inventory in-frame airbox to a single DNA filter, after which trimmed off the unique airbox breathers and crammed within the gaps. After some considered porting, machining, and fettling, the now 1,050 cc V-twin was prepared to start out blowing via clutches… which is strictly what it did.
“On the dyno with my mate Jamie at Dynomite Moto, the bike would attain 45 to 50 horsepower on the rear wheel and begin to spin the clutch,” Tom tells us. “We’d already upgraded to a brand new set of plates and efficiency springs however evidently that wasn’t sufficient. The answer was to make use of some Barnett plates and is derived, fitted to a stage two Harley Sportster, that allowed the XV to place its energy right down to the street.”
“The ability improve is mirrored within the sound of the engine too. Whereas most XVs sound poppy and hole, this bike has a nasty bark nearer to a cammed Sportster than the rest. One change I’d make could be the elimination of the only carb manifold—this was a provided half that isn’t an incredible match or design.”
“The XV750 isn’t designed to run a single carb, so I’d wager with a twin Mikuni setup we may safely milk much more energy out of the upgraded engine.”
With the unique Yamaha gasoline tank repositioned up prime, and a home made fender out entrance, all PBM wanted now was an acceptable shade scheme. The wheels have been already powder-coated in bronze, so preliminary discussions of black or crimson finally turned to one thing that will pop in opposition to the wheels. PBM’s go-to paint man—Justin at PopBang Classics—got here to the rescue with a surprising metallic olive inexperienced livery.
PBM dipped into their components catalog to get the construct over the end line. A 7” LED headlight sits up entrance, adopted by an aftermarket sprint, and clip-ons fitted with PBM switches and mirrors. The three-in-one taillights are a brand new PBM product, particularly designed to be seen from all angles.
PBM’s tackle the venerable Yamaha Virago seems to be wild and uncompromising, with sufficient of a growl to irritate the neighbors. However does it have the chew to match its bark? Tom says sure.
“As soon as it was run in, it was time to stretch its legs on the take a look at experience. It didn’t disappoint; energy wherever you want it within the rev vary, simply rip the throttle and go.”
“I used to be having a blast on some again roads, and once I went to take off with a little bit of gusto on the throttle, that entrance wheel lifted proper up and held up till I become second.”
“One of many solely Virago entrance wheels to ever go away the street, I assumed.”
