1981 Moto Guzzi V1000 G5

[Cdn850T5NT]

Anyone:  are there any negatives to having rear crashbars on a bike, and specifically a Tonti Guzzi?

[Groover]

i) I have the type of crashbars that are evident on the red Guzzi....

ii) I see on your Guzzi, you have the wider, Convert / G5 / Police bars; these are the ones I want to consider for my 850T5NT...

iii) the wide bars on the G5 - what is the max width of said bars, roughly speaking (pls and thx!)?

iv) are the G5 bars ONLY available to mount on Tonti frame Guzzi's with floorboards... or Guzzi's with the police-style long stand? (mine does not have floorboards, and per the photo, has the smaller stand that mounts considerably farther rearward, compared to the earlier short-stand Guzzi's);

v) are the bars on the G5 mounted the standard way?  Is there a kind of pin that is used, and that must be bought separately to mount the lower parts of the bars; and re the upper part of the bars - the mounting - will they work on any Tonti - or must a special plate be obtained, first?; and lastly

vi) what are the air deflectors for... i.e. for what reason are they used?

Sorry, lots of questions.

My wish is to get these wide bars, and to also get some wide bars at the rear.  The reason:  to protect the silencers (and to some degree, the cylinders), when the inevitable parking lot spill occurs.

Thx!

I'll try and answer to the best of my knowledge (which is limited to the what can fit in a peanut..)

i) The crashbars on the G5 are unique to the G5 and Convert. They are almost level on top (whereas the T3 have more of a slope downwards), and they have 2 threaded inserts per side for mounting the heat deflectors. They will fit on the T3, and should fit on the T5 if the frame top part has the holes in the right place for it (someone else should confirm this). If the bars you have are indeed the same as the ones on the T3, then they should be a bolt-on swap.

ii) & iii) I'll have to get back with you on the width measurement. Might be able to get that during lunch today or later today.

iv) & v) the G5/Convert police bars should fit on your top yoke/triple. No pin, or anything. I do love the bars' width, angle and reach to the seat, works perfectly for me. The triples clamps are the same for the T3, G5, Convert, etc (and pretty sure for the T4, T5) and are of the typical guzzi from that era two small clamp style, and the 81 G5 has a plastic cover over them. I don't think they are dependent on the side stand, though I think they are more suited for an upright seating position (forward pegs, or floorboards), so I do see your concern.

vi) Not exactly sure what they are for officially, but I love how they define the two V1000 models (G5 and I-Convert). I believe they are heat deflectors, maybe they help push a layer of fresh air towards the rider instead of heat scatter over the rider, all without blocking air flow to the engine. However, not 100% sure it's just what they look they do to me.

I believe the back guards are for saddlebag protection. I have seen some pretty scratched up so I'm sure they'll protect the bike too as you said (like foot controls, pipes, turn signals). I considered adding them too during the restoration and also some factory hard bags, but they were hard to find in good conditions so opted for the bare look for now, and just get something later fully loaded (like an EV or something)

Beautiful, especially in 4 months!

Thankyou for that detail, Groover.  It was, for sure, a carefully chosen colour!

StratoGuzzi:  your SP1000 looks great.  I like SP's, SPII's!

Related to Groover's G5 - I am wondering about the (front) crashbars you have on your bike (and please, Others, kindly jump in, too):

i) I have the type of crashbars that are evident on the red Guzzi....

ii) I see on your Guzzi, you have the wider, Convert / G5 / Police crash-bars; these are the ones I want to consider for my 850T5NT...

iii) the wide crash-bars on the G5 - what is the max width of said crash-bars, roughly speaking (pls and thx!)?

iv) are the G5 crash-bars ONLY available to mount on Tonti frame Guzzi's with floorboards... or Guzzi's with the police-style long stand? (mine does not have floorboards, and per the photo, has the smaller stand that mounts considerably farther rearward, compared to the earlier short-stand Guzzi's);

v) are the crash-bars on the G5 mounted the standard way?  Is there a kind of pin that is used, and that must be bought separately to mount the lower parts of the crash-bars; and re the upper part of the crash-bars - the mounting - will they work on any Tonti - or must a special plate be obtained, first?; and lastly

Sorry, lots of questions.

My wish is to get these wide crash-bars, and to also get some wide crash-bars at the rear.  The reason:  to protect the silencers (and to some degree, the cylinders), when the inevitable parking lot spill occurs.

Thx!







TIA, All.

Sorry, folks... I need to clarify:  when I said "bars" above, I had meant crash-bars not handlebars.  Accordingly, I have taken the quote, above, and inserted "crash-bars" where previously it had said "bars".

Apologies re any confusion this has caused :|

Cheers!

[Groover]

Since I already did the "work" on the handlebars...   I'll post the pic/dimensions here for reference. I'll get the crashbar width later... Sorry for the confusion. When I read police bars, I went with handlebars in my mind.

[Cdn850T5NT]

Thank you so much for your kindness in doing that work, Groover...   Sorry re the confusion 

[Cdn850T5NT]

Beautiful work on the bike, BTW.  I see you put T3 instruments in...  Originally the G5 would have had just a speedo, no tach....?

The '81 (2nd Generation G5) has the dual gauges like the T3 and the Le Mans III style taillight. The 1st generation G5, have the larger square dash and the cowled tail light as seen on most Converts (except the 81 Convert). There are some variants and other details, but that's it in a nutshell.

 nice G5. I really have to tear into my convert.

     Groover,    Your G5 is very well done 

     Your endorsement and praise for that model, factored into my decision to pick up the only G5 I ever saw for sale locally.

     I hope when mine gets reassembled and down off the lift, it runs as well as yours,,, I know it will never look that tasty 

     In regards to the air deflectors, I noticed similarities in the size/angle/location of the deflectors on my G5 and the design of the lowers on my CX100 and the lowers of all Lemans 11's & SP's; all of the same vintage.

     Just a wag, but I'm surmising that with prolific use of the wind tunnel back in the day at Mandello, those angle wind deflectors were probably designed, to also help put downward pressure on the bike, my opinion has always been that "nothing" sits down firmly on the pavement like a guzzi, it seemed to be part of the design. fwiw ymmv

I never realized that, but comparing those models you mentioned they do all have similar placement and angles. Looks like even the Le Mans IV & V, Lario have a variant of that. I'm gonna call them Air Dam Heat Deflector Foil Spoilers from now on

Just measured the total width of the front Crashbars, and it's 28" (this is for the factory G5/Convert ones as on mine).


Hope that helps.

That's a beautiful bike, man...

Many thanks, Groover.  Sorry for the extra trouble.  The reason I wanted to know is that it has to fit a doorway.  The bike is stored at 70 degrees F in a walk-out basement.  Would indeed be problematic if it would not pass thru the door!

Re the bottom mounts - are those special bolts that are used to bolt the removable (lower) frame elements to the down-coming (battered angle) frame elements?  It seems to me that the bolts may be male on the end that connect frame element to frame element - and then female on the end where the lower crashbar mounts to them?  Do I have that right?

[Cdn850T5NT]

Oh, now I can see how it's done.  There is a spacer.  See the attached graphics.

GORGEOUS!!!!!

In the words of Paul McCartney.......... ....."It's a clean machine."    Very nicely done.
