I don't mind the bike, but I'd prefer a bench seat to make it more practical and have a better aesthetic appeal.  And where the hell is the brake light and turn signals?

These are custom builds, so, they'll build it however you like.
And yes, I'd take it with more bike behind the rider seat.    I'm thinking a tasteful tail clone/hump, similar to the V7 Racer, but, w/o the stupid number plates molded in to ruin it.   I'd run my racer with the plastic tail piece on it if it wasn't for those.

Looks really loud...

Just go an buy one of those king and queen convert saddles off of e-bay 

How much is one of these Frankenstein's Monsters going to cost?

Power to weight ratio should be great, to bad about the trendy styling.

[Shorty]

Every time I see a bike like that, I picture the rider hitting a big ole bump in the road, and being thrown 'nads first onto that rear tire.  An overabundance of caution, I suppose. Abbreviated rear end does nothing for me. I'll pay the 5-8 pound penalty and have an honest fender and seat. Front of bike looks nice.

I see a long stripe of mud up the back of the rider every time I see one of these bikes with a rear end like that. I think the bike would have looked a lot better with a longer seat and a proper mudguard. But I guess many of these bikes rarely get of the display stand.

Didn't Ed and Todd have a very ugly and very public divorce like 5-6 years ago?!?

That is correct, although I think it's been longer than that.  I don't believe they are on speaking terms at all.

Looks really loud...

Not really all that bad.  Nice throaty rumble.  I suspect if it isn't sold by then, it will be seen at Lake Henshaw, along with the V-7/11 build.

Too bad there are so many negative posts on this custom Guzzi. It's wonderful that someone (GT and/or Todd or whoever) took the time and the expense to build a custom Moto Guzzi. For this bikes intended purpose, it looks wonderful. They will likely find an eager buyer in and around the Hollywood California area. Maybe for others they'll build one with a Russel Day Long seat, Wixom bags and an old Vetter fairing. Turn signals you say. I'm sure some old LAPD style Dietz lights can still be found.

About the claimed power.  I don't know, there's a company out of Germany I saw post on FB that makes a Big Block (1800) kit for the Guzzi 1400 and they claim big HP and Trq numbers. Does Piaggio still use HP and Trq figures optimistically 'measured' at the crank? It would be nice to see an actual dyno graph of how the bike makes its claimed power. Though that's true for just about any bike.

The Griso is 109 h.p. vs 98 rear wheel.  I think its about the same 10 h.p. drop for the 1400

[Kev m]

Shorty - I prefer a full seat and an actual fender too, but I don't think I've ever been bounced out of my seat and landed rearward on the back of the seat. Just saying.

Piaggio?!? You mean everybody. It's industry standard and has been got sometime. Hell I believe it's even regulated in the EU and Ducati a few years back had to publish revised HP figures found using the regulated method (because their method had been even more "optimistic" than the regulated method).

Anyway, as long as you're comparing apples to apples I wouldn't call it optimistic.

[JohninVT]

A six inch longer seat and an actual fender would do wonders for the looks of this bike.

The problem with Todd has always been his wild claims not matching reality.  Saying this bike has 140hp is a prime example.  For some of you, that's not a big deal and you can look past it.  For others, like me, it's a deal breaker because I'd never have anyone build a motorcycle for me that I couldn't trust. 

As a static design piece it's very interesting. 

[Groover]

I fixed it, now it's good. - I added a convert tail and an LM1000 tails; liking the convert one

Thank you for this. 98 rwhp on a Griso explains the fun quotient at high revs.


Kev, I fully expect Hp and Trq figures from any and all mc manufacturer to be optimistic That's why seeing an actual dyno chart done in the real (non Marketing) world tells more of the story. Seeing the Hp and the Trq curve throughout the useable rpm range shows a lot. At least enough to peak interest. I see too many guys that brag about peak HP and Trq numbers but when you look at the details, it's often in an rpm range the bike may very seldom see.   

This same custom Guzzi on the Victory forums is being very well received and apprciiated for the work done and the unique look and nature of it. Yea, I know, different strokes and all that. BUt I hope they sell a good number of these custom bikes. It would also be great to see the exposure for the Guzzi brand if this bike makes it into a few of the magazines. 

If I had the disposable income to get a custom Guzzi similar to this I'd certainly do it.

[oldbike54]

 So what happens when and if someone actually puts this thing on a dyno and it really is only making about 105 HP and 95 LBS feet of torque ? Stock this engine makes about 95 HP and 89 LBS feet of torque , my understanding is that due to limitations created by cylinder head design that it is very difficult to gain much flow . Until I see a real verified dyno run , the claims of a 40% plus increase in HP seem like fairy dust . If I'm wrong so be it , but I am gonna need some proof .

 Dusty

[TN Mark]

Dusty,

     I agree, that's why I mentioned the dyno graph and the German company making claims of  huge Hp with their 1800 big block kit. Unless it's real, it's fairy dust as you say. Don't tell me 140 Hp and then show me 105 Hp on a dyno graph.

[Huzo]

Looks better than most of what the factory is offering.

Touche'

[Huzo]

Kev buddy , I literally have no idea what you are trying to say here 

 Dusty

I think the implication of Kev's statement is..
The damn thing is extremely desireable even though the real world figures will not be as claimed.
 I don't think anyone is decrying the Hp/ Torque that the mill will produce, but why lie about it..,?

Forget this custom for a minute. I'm saying that in the end of all manufacturers are giving crank numbers that are borne out later by independent rwhp tests that show a predictable frictional loss then the original numbers weren't optimistic.

That's all I was saying.

[bad Chad]

So some of you think it makes sense to put a motor producing a claimed 140 hp in a 50 year old frame, designed to deal with 55hp? 

I see something breaking when you least want it too.

Sorta. I'm saying forget this one off, but something like this from the OEM with realistic numbers would still be damn desirable.

Moreover I'm not really impressed by or interested in a one off bike. With enough money you can do a lot and ignoring the burdens of regulations and manufacturing you can do even more.

[bad Chad]

Maybe it is just that, a dream.

Bikes are not supposed to " make sense".
A beige Toyota Yaris makes sense..
And also..
Why do we spend so much time arguing the toss over power claims of stinking old Guzzies..?
They are all weak as piss compared to Aprilia RSV's, Suzuki B Kings, et al..
That's not where the appeal is.
Again it's not the relatively meagre output that people shun, it's being bullshitted to that bights...

[oldbike54]

 Something else I'm curious about , the site claims a 1/4 mile time of 10.56 seconds . Have they actually performance tested the bike , or is that based on some fictional power to weight ratio ?

 Dusty

[john hooper]

I hate that single seat look it makes it into a toy for the jetski generation

[PeteS]

The specs also list a 10.62 quarter. A timing slip should quiet the skeptics on the HP number. You won't do that with a 100 HP.

[Idontwantapickle]

That's purdy and all but it's missin a lot of steel that a CARC bike has to keep the wheels pointed the same direction. I'll not ride that, it's just waiting to break.

[JohninVT]

I was in a rush this morning so my post was brief.  Now I'll say a couple more things;

Beetle knows more about 1400 re-mapping than anyone on the planet.  When I jokingly asked him if he could remove the speed limiter on my Cali he said yes but it would probably disable the ABS(He wasn't sure.  Probably because I'm the only idiot who wants a 140mph Touring, so he hadn't researched it).  I find it incredibly hard to believe that Todd "re-mapped" the ECU to magically produce 140hp while retaining any sort of drivability and retaining the traction control and ABS.  In fact, I don't believe the 140hp number at all.  Not even if it's bored out to 1800cc.  A 1400 puts out high 80's to low 90's on a dyno.  Getting an additional 50+hp from an engine isn't possible with a 20% bump in displacement.  Nor is it possible with fairy dust fuel mods.  I'm not sure you could get 50hp using low compression pistons and a turbo running 10psi.  How the hell would you get rid of all the heat from a 140hp air-cooled engine?  It's not like the engine has big radiators hanging off it.  Common sense says power=heat and you need a way to get rid of it if you want to make power more than once.     

Does anyone here really believe that any motorcycle containing a Moto Guzzi V-twin with a shaft drive system weighs less than a 899 Panigale?  20 POUNDS LESS than an 899 Panigale?  Does anyone here really believe a motorcycle with a Moto Guzzi V-twin...with a shaft drive system...can cut a 1/4 mile time within 2/10ths of a second as a Panigale?  I'd be shocked if the 1400 engine and drivetrain alone aren't over 250lbs. 

The work looks very high quality.  It's cool to look at.  I think Todd has a portable meth lab in his shop and he was overcome by the fumes when he typed out the spec's on his website.                 

[Rick4003]

Why do you think there's a lot of steel missing? Anything rear of the swing arm pivots and shock mount is really only there to hold the seat.

Look at the Bellagio frame. It is very close to an identical match.

First picture is the original setup of the Bellagio and it even have the small aluminium disks that sits in the tip of the frame triangle.

The second picture is a custom made by Officine RossoPuro. Much better seat and fender solution in my opinion.

I still believe that the gtm01 is just a bellagio frame with an 8v engine mounted. It looks so much like the Bellagio frame that I find it hard to believe that they have made it from scratch.

Well, when you show a GTM01, you know there has to be a GTM02. Stay tuned. Anyway, I'd love to see the GTM01 on something like Willow Springs along with an actual dyno graph. I don't have any inside knowledge on the GTM01 engine but I would doubt it's stock. Who knows, there are a lot of things that can be done with head work, throttle body size, cams, intake, exhaust, timing and piston/combustion shape etc etc etc.

I know for a fact that a stock Victory 106 puts out about 62 Hp at 3000rpm and about 112 Ft/Lbs or Trq before the fun is turned off at 5500rpm. With very mild cams, an air filter, +4 timing, slip on mufflers and a PCV tuner Hp goes to about 107 at 3000rpm out to about 114 before the fun shuts off. That's a 45Hp improvement at 3000 rpm with 'low hanging fruit' parts totaling about $1000 and a day in your garage with basic hand tools. Trq in this same scenario goes from 65 to 114, (+49) at 3000rpm and it stays nice and flat till the fun is shut off.

All this at LESS engine heat (-50%) and better (+4) fuel economy. Remember, no matter what you think of your stock Guzzi motor, it's NOT tuned for power. It's detuned for government regulations. The numbers I posted are from 'tuning' in 4th gear. The 'power run' for the numbers in 5th gear will increase them both 3 to 4.

Add displacement, tank risers and 'touring' cams and numbers like 135 Hp and 135 Ft/Lbs of table top Trq are very common. Tuning and parts selection will determine where and how these 4 valve motors make power.

So yea, I do believe it's possible to wring more power out of a Guzzi 1400. 140 Hp peak? In the hands of the right tuner with the right parts, yup.
