The Gpz 1100 was one of Kawasaki’s first sport-touring motorcycles, but there’s little left of this particular unit after ending up in the hands of custom motorcycle builder WrenchMonkees. Turned into a naked powered by now a 125 hp Gpz engine upgraded with an 1170cc Wiseco piston kit and featuring more tweaks than you would imagine, this might very well reflect how things get done in Denmark.
With sports wheels and suspensions, this roadster should know how to bring riders the most benefits from that powerful Japanese inline-four engine, so in the end it is all a matter of style, which is quite unique, especially if we look at the backend. This is contoured by the WM rearframe and characterized by a flat seat and custom back fender as well as by the LED taillight. Up front, there’s also a WM fender, while the fork wraps make it look like one of those Mad Max bikes. In between, there’s a stylish Zephyr fuel tank and a very enthusiastic rider. Please read the specs after the break.
Copenhagen-based custom motorcycle builder WrenchMonkees brings Japanese power to the world of café racers with their Monkee number 2. Although it started life as a Kawasaki Z1000 A, there’s little left of the original bike, not even the engine. This was replaced with that of a Z1000 J model, which was upgraded to around 110-115 hp by fitting a 1075cc Wiseco piston kit.
The café racer image was achieved with the use of a Norton fuel tank and a Ducati Monster headlight while the rest of the body parts, but also the mufflers, LED rear light and even the custom paint wear the WM fingerprint.
We can’t help but think about the uncomfortable riding position, read the specs again and appreciate the fact that it has a big engine as well as a retro look until finally reaching to the conclusion that this may very well be something that our favorite Hollywood star would ride to the studios everyday.
WrenchMonkees clearly has a passion for bringing old classic roadsters back to a new kind of glory by using a few tricks that they have in their sleeves. For instance, this Kawasaki Z1000 A now benefits of 105 hp as a result of installing a 1075cc Wiseco piston kit to the original motor, which is now fed by Z1000 J carburetors and filters air using K&N pieces.
The Copenhagen-based custom builder has the tendency to turn every bike into a café racer and this one looks, sounds and we reckon it performs as one too. Most likely, the sports bike front suspension and custom rear shocks also bring a major contribution to what looks to be a very angry piece of machinery.
Stylistically, the WM fingerprint is left by the all-new tail and seat as well as by the custom paintjob. Ride this bike like you stole it and people will believe you actually did simply because they would have probably done the same thing if they were you.
Turning a roadster into a racer might not be the easiest task, but it all comes down to the moment you start that engine and it speaks more aggressively to you than it ever did before. The bike in case here is a late 1970s Yamaha XS 500 now wearing the WrenchMonkees signature on it. This translates into an entirely rebuilt and custom painted engine to match the bodywork’s beautiful gray, WM stainless steel exhaust and muffler, which gives the bike its racy sound.
Light, compact and disposing of a fair amount of horsepower (approximately 45-50hp), the WrenchMonkees Yamaha XS 500 features Brembo brakes both front and rear, while the standard front suspension was kept and the stock swingarm now works closely together with two Gazi Gas rear shocks.
In the end, custom bikes are all about style and this one stands out mainly because of the WM tailunit and seat, while the clip-on’s, throttle grip and levers are all nice touches to have on a bike like this. We never thought a round metal plate behind a small headlight would look so good, but it does and shows attention to details and imagination along with it. We like it.
As you can probably remember, we have already wrote about a WrenchMonkees Yamaha SR 500 that caught our attention and it turns out that motorcycle number five in their list of customs is yet another such model. This one looks like a rather civilized approach towards the 1970s bike and stands out mainly thanks to its Mag type BMX wheels and a much more attractive custom paint.
Of course, the back end of this motorcycle is entirely new and in accordance with the WrenchMonkees style as you can see by looking at the rear frame and fender as well as to the seat. The lights all around the bike belong to WM as well.
The heart of the original bike was revived and given a tune-up and a heat resistant layer of paint. There are also modern components such as the Brembo front brake caliper and Brembo 320mm disc, but why don’t you check out the specs for more details.
It seems the Kawasaki Z 750 B is a great bike to work on for Copenhagen-based custom builder WrenchMonkees as this is not the first time we write about their creations based on this particular Japanese bike. In this case, they choose bobber-like wheels as a first step in turning classic into custom while the unique rear frame and seat leave the unmistakable WM signature.
The original engine was kept, but it is now restored and covered in black heat resistant paint. It develops approximately 50 hp and breaths through K&N filters and WM megatron mufflers, this time not covered in exhaust heat wrap.
Clearly, style beats performance on this custom motorcycle and the final touch is given by the in-house rear fender and clean custom paint. Those small head and tail lights are supposed to make the wheels look even fatter and the thing is that this is one of those bikes that you rediscover each and every time you look at it. Specs are attached after the break.
This old Yamaha SR 500 saw an unexpected revival after getting in the hands of the guys at WrenchMonkees in Denmark. Although we’ve seen this motorcycle model being transformed into a café racer, a chopper and even a scrambler not just once, the custom motorcycle builder decided that there’s nothing wrong with the class and only gave it a meaner custom look using a few tricks that they had in their sleeves. For instance, the WM rearframe, seat and fender as well as the rear light all indicate the attempt to make this thing one-of-a-kind and this is just the rear end that we’re talking about. Up front, there’s a stylish and very small WM fender as well as a headlight that stays in tone with the clean look of the bike.
Although apart from the K&N filter, the approximately 40 hp entirely rebuilt engine is the same as on the original bike only that on the WrenchMonkees Yamaha SR 500 it breaths out through a megatron muffler with heat wrap. Also, the battery was eliminated, so the single-cylinder is started by kick only. Riding a unique motorcycle nowadays means plenty of benefits that the old timers didn’t had: the Brembo front disc and caliper, not to mention the ABM steelbraided brakehose.
The WM heat resistant custom paint and all the hidden wiring is what riders who order these things look for and this bike sure can brag about that. In the end, you don’t need to look at it twice to understand that this SR 500 can be ridden on a variety of surfaces such as asphalt, dirt, gravel, but we’d rather take it to the beach and call it The Motorcycle Beach Buggy.
Although Kawasaki never designed the Versys to be a naked, but a middleweight sport-touring motorcycle, WrenchMonkees have come up with their own approach towards the original Japanese idea. They got rid of the strange looking headlight and half fairing then brought not only their own headlight and headlight brackets, but also a new front fender, Rizoma handlebar and clamps as well as front and rear turn signals. Further enhancing the bike’s now much sportier nature is the WM seat, while the custom paint and exhaust heat wrap make this a veritable midnight naked, if you accept the term.
The WrenchMonkees team gave a unique touch to this late 1970s Kawasaki Z 750 B not just by rebuilding the engine and adding their very own megatron mufflers, but by turning classic into custom using what we begin to consider the WM routine. This implies a new rearframe and fender which help at giving each of their bikes a unique look, while the aluminum battery box helps at meeting the customer’s requirements.
Good looks are part of just a point met on the Copenhagen-based builder’s check list. Because comfort is another one, this bike gets WM seat, footpegs and also handlebar and grips. The riding position looks quite natural and the bike is overall exclusive in its simplicity. You won’t find any wires hanging on for dear life on their way to the WM headlight and taillight and we have to appreciate that, just as we cannot complain about the WM heat resistant custom paint. This, together with the 19-inch cast alloy wheels, makes a Kawasaki Z750 B look like something that Brad Pitt would ride.
What originally started as a Triumph Bonneville TR6 ended up in the hands of the WrenchMonkees crew in Copenhagen, Denmark and was completely transformed to suit the style of one lucky customer, who ordered it.
Although this custom bike builder seems to follow no pattern when trying to get the best out of each specific bike, we did notice that – like on most of their creations – this Triumph’s engine has been completely rebuilt and it now has a Morgo 750 cc kit installed. Fed through Amal 930 carburetors, it develops a claimed 50 hp, which is enough considering that the thing has been stripped down to its bare minimum.
Also, they use their very own hardtail rear frame, fender and light, while in this case the seat, steel battery box and wiring harness add on to the exclusive look. In fact, you’ll find people saying that such motorcycles projects never get finished because they represent the ideas and work of a proud rider, but little will they know that for the right amount of money WrenchMonkees makes any rider look like a skilled motorcycle builder.
