Guzzilla
Dynotec Moto Guzzi
158bhp, 105lb-ft, 168kg – from a Guzzi - what?
von Olly Crick
GERMANY'S Moto Guzzi tuning specialist, Dynotec, have produced a bike so engineeringly raw it's undeniably and exceptionally cool. It bristles with technical innovations and clever solutions to making a bloody fast bike from a lumpen V-twin motor that's been all but obsolete since the mid-1970s.
PB met Guzzilla at Hockenheim, which isn't the circuit it used to be. Gone is the famous forest section, replaced by a long left hander. This is worthy of note because there's no starter on this Guzzilla (one of nine that currently exist). You fire it up using a pit lane engine starter, MotoGP-style, and I'm terrified of stalling this high-compression monster on the tight hairpins that link it to the old track. Not just because there's no way of starting it again, but also because I'm really scared of dropping it as the revs die away on the slow apexes.
Dynotec began making Guzzillas in 1995 and continually develop more ideas for them. If you want one, they cost between 25,000 and 45,000 euros, depending how high a specification (and how much road kit) you choose.
The engine,originally a 1000cc unit from a Guzzi Daytona, is bored out to take 100mm diameter pistons. With a new 82mm stroke crankshaft, the capacity is hiked to 1288cc. To help the airflow keep up, 5mm larger inlet and exhaust valves have been slotted in. Dynotec fit their own special camshafts and a Sachs racing clutch. The extra stresses induced by all this mean the crankshaft requires bigger front bearings than stock, the pistons need stronger Carillo conrods and Dynotec's own uprated oil pump is fitted to stop everything disintegrating. The resulting lump makes a claimed 158bhp at 8400rpm and 105lb-ft at 6600rpm.
To force the maximum volume through the ram-air system (48 litres), the carbon fibre seat unit doubles as the airbox. The front bodywork, also carbon, channels air through the front hoops, straight into it.
The Moto Spezial fuel injection is hidden behind the side panels. The software it uses was developed on the Dynotec dyno. It's a closed loop system, so it's clean and efficient, too. The exhaust is also bespoke and carefully developed. There's a straight through 60mm diameter option that eliminates the bulky collector under the gearbox and releases another 5bhp. The front tubular sections are made from titanium, the rest are stainless steel.
The completely new steel chassis is hand built by Dynotec. The original Daytona item wasn't suitable or strong enough for Guzzilla's requirements. The new chassis has a 7cm taller seat height than the Daytona and a claimed 270 per cent stronger braced headstock. The head angle is 23.6 degrees and the wheelbase 1420mm, which makes Guzzilla's dimensions as sharp as an R6 and as long as a Mille R. The Dynotec aluminium swingarm is shorter than most at 480mm (a CBR600RR is 580mm), but Guzzilla feels stable at any speed.
Front brakes and both wheels are PVM. Calipers are top spec with titanium pistons, while magnesium wheels save unsprung weight and enhance the handling. The rear brake is a tiny PVM caliper off 125cc GP bike and a Dynotec 180mm disc, but with so much engine braking, a rear disc is hardly necessary.
The bike weights 168kg with everything bar petrol and is suspended by Öhlins front and rear. Dynotec worked closely with the swedish firm to ensure the suspension is just right and have mounted the rear shock without a linkage. Lots of wheel travel and shifting more oil improves damping, they say. The front 'superbike' forks come with a similar set-up to that used in the German superbike series. And it's works. Initial nerves are helped by slipping the clutch through those tight hairpins until I get used to it. The steering feels heavy to start with but the traction out of corners is phenomenal. The racing pattern l-up, 4-down gearbox made a fool of me a couple of times, but once the bike had my confidence I wanted one, and still do. Giving full power on the straights and tucking in behind the long fairing, you can feel every single throb of the engine. The sound it makes is indescribable, so I won't even try.
But it's not perfect and that's what I Iike about it, it has loads of character. It still sways like any other Guzzi when you rev it, it's too tall and doesn't feel like anything else. The raw unpainted metal on view is great. And it says Guzzi down each side. Spend an hour on www.dynotec.de and see if you feel the same. OC

Thanx for the info!! Mine will be the poor mans version and i would be happy with 125 hp
@Pete...you will have more knowlidge than i...i just found these pistons and have to see if they are forged...i doubt it but will look for it!@
-
Custom made carrilo's says big dollar i guess...might be cheaper to use custom made pistons
600 dollar for 4 pistons.... -
Could i use Sport 1200 pistons for a big bore?
-
Wow...that looks the dogs bollocks! Like an old English friend of mine use to day...
Question? That rear shock absorber looks very short? How long is it? Cause i could use a very short one for the Centauro monster
-
To be honest I don't think the 'C' kit is worth the time, effort or bother. Most of the people I know who have changed on way or the other actually preffer the standard 'A' cams.
If you want to mess about with the fueling I have a PCIII for a Hi-Cam that I aquired by a long and circuitous route that I won't bore you with. For reasons I also won't bore you with I'm selling it and donating the money to 'Medicienes sans frontiers' for the Haiti appeal. So far nobody has put their hand up so if you're interested make me an offer. It's brand new, still in the box and cost me about $3-400. I think the Hi-Cam PCIII is model specific so it won't work on the pushrod models, (I'm not sure of that though.) and they don't make 'em any more.

Correct, the mapping is the difference. C kit cams might not be available, but mgs01 cams are. And cheaper then the c kit ones. I just ordered a set to see if they deliver them.
Hi Paul! Long time no see/talk!
You know i just fool along compared to you guys so thanx for the advise!
In a way i ''know'' a company who claims to build custom cams and want my to be big bore for testing so maybey in time i have more info about this!
-
Thanx Pete...These are the things i can work with! Like i said...i'm not going for the red zone / 9000 revs! I didnt know that the C kid cams still were avalable!!!
I have the C kit ecu here but that nothing more than the normal ecu with a different mapping?
-
Thats what i think too but like i said...the technician says that those revs are not so high compaird to other bikes. I'm also not much of a racer its more the building than using it to the edge. I'm not trying to invent the wheel again but there's so much i dont know....just by trying and asking i learn
-
You know about the cog forum, don't you? You can stay here as well of course
Discrimination....he doesnt want me here
Just kidding...i just look for info at any place i can think of and i do like the V11
I only have the problem that i cannot leave a bike as it originaly was cause there are always things i want to chance...its a disease that costs money and time and thats also the answer for the why i takes so long to have a riding bike 
Also have a discussion with ''my'' technician about the use of Carillo's....he claims that the original Guzzi ones are strong enought to use in a big bore and wants to blueprint evreything inc the rods but i'm not so sure about this?
-
Sure...but the Centauro monster has no engine at the moment. The engine that was in the monster is now in the Quota and i started with a new V11 crankcase for the bigbore that should go in the monster!
-
Hello Gents!
Thinking about a big bore for my centauro monster i am now looking for big bore pistons....any tips? It would be a great help
And yes....i have a connect with this forum: the six gear
An indication about my centauro monster:
Plus to make it even more complicated....I had the idea of building a daily ride so i at least had something to ride...i failed
so now i have two bikes in varouis states of not finished!The ''daily'' ride:
-
Man! Just as on Motor forum: my deepest respect for the build of this beauty
-
Dare you! Double Dare you!!!
Be easier in a Sport i Pete
Its not a v11 project i'm working on, i do use a six gear, and its not just bolt on but a Quota with a Centauro engine is not sensible but the thinking alone is already good fun...Imagine the driving?
It was originaly my intention to build a standard Quota to have a daily ride next to my first project but somewhere down the line it went horrebly wrong and now i have to projects and still no ride
-
History repeats...i'm building a special, my first, and Guzzi comes with the centauro..now i'm working on my second special...here's the Griso...
Anyway...from what ive seen its to long...just envy...i hope it sells a lot and give Guzzi that Boost it deserves!
Special...........if i kwew how i put a picture here...but its to be seen at:http://www.gewan.demon.nl/Guzzigek/index.html under never ending story...

Hello Guys,
I have the opportunity to buy a pc III from a guy i know but its not moto guzzi...now i was thinking of putting new cables who fit the guzzi ones on that commander? Maybey longer to? Are they avaliable?
That commander would be fitted on the V11 of my girlfriend...a 99 model but all mapping starts with the 2000 model? Is there any difference?
Thanx,
Peter

Actualy that what my thoughts where as well....so i use the standard stainless frontpipes with a crossover....and a set of supertrapps....something the guy who knows all in my begintopic allso diaproof off...
Also a picture of my guzzi horror
-
As for the exausts...i have a crossover and believe that the original centauro headers would just be fine for my purpose...i want torque en pull power..cause i'm not mutch of a real driver who hangs next to his bike in corners...
The 50 mm headers looks rough but they are more for top speed....as i believe to have read here!
-
Well..i hope that the picture i want to put here also comes here so you people can seen what's keeping me out of my sleep and that i have a long way befire i can fire her up!

Hello guys,
I was in a workshop of guys who have a serious reputation here in the low lands and one of time told me to put 50 mm exaust pipes, from the head to the crossover!, on my centauro bases engine? But i always had understand that the bigger that pipe the more topspeed you would have?
And they are totaly into racing, they even build a diesel race bike, so i assume that they just thought i want top speed...
Witch i do'nt want...i want torque!

Hello guys,
Dont know it this topic is right here but i realy could use some tips or help about shipping from the states...
I'm not a very welthy guy and thats why i buy sometimes parts in the states, even japanese
,cause i dont have spare money to work on my special ....did that several times and it went nice...Now i bought a frontfork in texas and the seller, an honest guy to me, told me that the shipping is even more than the buying price trough fedex, ups is even more expensive....any tips?
I'm in Holland!
Thanx in advance!
Peter

Hello People,Knew that italian paint could be different that ,normal,, paint and the V11 of my girlfriend will be powdercoated next winter due to she hates red...
But the paint on this bike is unbelievable...frame,subrame, rearbridge, cardanhousing, wheels...it just comes off due to corrosion and rust...
I've seen bad wheels but complete plates of paint coming off...the cardan housing is bare alu now..
Could it have anything to do with leavind the bike outside or roadsalt? The bike has only 6000 miles on its tacho...
Next winter it will look a bit different than stock
tips for big bore?
