LEMANS 1000 FRONT END IMPROVEMENTS
« on: March 08, 2015, 03:14:17 PM »
apart form a GSXR front end as described in this article, http://www.guzzipower.com/GSXR-Ed_M.html

has anyone got any tips on improving the front end of the lemans? Any other front ends that fit/work? better springs?

mine currently has the FAC air assisted forks and I can't say that they're great...

thanks

+1.

I have FAC dampers and Progressive (Wirth) springs in mine.  It will never be plush but it's loads better than OEM Paoli (?) and the weak springs.

Forcella Italia made a set of forks for that bike. I have a set on my LMIV. The best improvement is a 17-inch Astralite front wheel, though. Cuts about 10lb. of unsprung weight.

thanks guys,

greg, astralite sounds like a good shout, may well give it a try... do you rate the 17inch front as better than the 18?

I do. Much better selection of sticky rubber, too. Mine was designed to work with the small stock rotors. That wheel will be difficult to find, but maybe find one for another bike with more modern rotors and make whatever it takes to fit to those rotors?

Another option would be the triples/forks/wheel/rotors/calipers off of a V11 Sport. It would adapt on pretty easily. Might be tricky getting the bikini fairing on, though. Watch eBay for the parts, and it would not be that much money.

This might be an option if you want to improve the front end and  keep the original look

HH Racetech in Germany offers the "Kit 4" for all non adjustable Guzzi forks  (35,38 and 40 mm) http://www.hh-racetech.de/HH-Race-Tech-Gabelkit-4/Gabel-Kit-4-Moto-Guzzi/Moto-Guzzi-Le-Mont-BJ-ab-1981---Gabel-Kit-4.html  - they build a cartridge kit in the original fork, compression and rebound adjustable as well as the spring preload.
I have it in my track bike, it works good. I like that it does not attract too much attention.



You need some time when you send your fork away, it takes a while at HH Racetech......

Now if you send off your shocks for a couple of months you'll need something else Guzzi to ride in the meantime and if you didn't have a spare like me ...........it would be a win-win.

good idea, although as soon as I find a decent v11 sport front end, I'm gonna have a go at getting it on my 71 ambassador!!

Can you not buy and install yourself?
$1200!!, they may be good but not $1200 good.

I've just re oiled my original LM2 cartridges after advice from this forum and after fitting an Airtech repo Mk2 fairing, which has saved a boat anchor in weight over the front end, I'm expecting a vast improvement from them.

Greg - when you say "easy" how easy is easy? What needs to be done to make it work? Only really want the forks (and yokes), I'd want to use my existing spoked wheel and brakes. No fairing on my bike so that's not an issue.

There is a front end from a 1997 1100 sport injection on Reboot at the moment, 525.00 for the forks and yoke, wheel spindle for 17.00 and a front mudguard (slightly split) from a 1995 11oo Sport carb for 32.00.

This is for a LeMans I frame.

I dont think so. They only offer the complete package. I agree, it's a lot of money and there are other options as well. Before the purchase, I was thinking about fitting a M1R fork from a 1100 sport or a BMW K 100 into the trackbike. But the used stuff on Ebay for ~ 200-300 needs more or less always a complete overhaul, plus all the adaption work until the front end is complete -  it sums up not too far away from the HH Racetech offer. As the entry fees are quite expensive, it's beneficial to have a good working suspension as quick as possible.

For road purposes progressive Wirth springs in combination with FAC's work quite good, I have this combo in the 1000 S.

I wonder if a 35mm cartridge assembly from something japanese might work- most are bigger than 35mm though.  I wish the cartridge emulators worked on these forks.  they mde a big difference on my Triumph.

I think those would be WP forks. I'd recommend later forks, instead. If you would be keeping your wheel, then you need to find bearings and spacers that will work with whatever spindle you use.

You also have to adapt the triples to your short-neck frame. Possibly, that would be as easy as pressing the LM steering spindle into the new forks, but might be much more, depending on what forks you get.

When I did this to my Eldo, the easiest and best way for a lot of reasons was to use spacers above and below the steering bearings to adapt it to the short-neck frame.

Easiest

Stock 40mm forks are perfectly fine. I would recommend Maxton internals : http://www.maxtonsuspension.co.uk/files/gp20.htm

I have them on 2 race bikes and they are excellent. Price is below $1000.

I did a gsxr front end on my cx100 including the radial calipers for best brakes. I used 18 inch boranni wire wheels for looks and lightness. EXCELLENT RESULT as well.

I have talked to their classic bike expert and they dont really have anything other than springs unless you want to have a custom set of forks built.

my 2c on the astralites would be concern that the lack of a cush drive would make short work of your splines in daily use.... but it obviously depends on how you plan on using your bike....

They were very responsive to my emails and seemed like a pleasure to do business with in any case.

Astrilite is no longer making wheels.  Its a bummer and I kick myself for waiting too long to order a set.

I used a UK company, MCT, to modify my Tonti Cafe racer front forks. It wasn�t cheap but they made a fabulous job of squeezing Suzuki 600 GSXR internals into the original Guzzi forks.

My brief to them was, they must still look classic and not modern but they must handle sublimely.  I did have to replace the bright blue Suzuki adjusters with some I had anodised a suitable satin black.

Job done.

They did a cracking job of the rear end too!
