Ground clearance

Cantrestand1_ani Limited ground clearance. This a regular phrase in almost every Norge test report I've seen and it's quite a common complaint for Breva 1100, too. They share the same frame and suspension, but Norge is 15 kg heavier, which may make it a bit more prone to grounding. The actual problem is the centre stand - Moto Guzzi did remove the centre stand totally from the 1200 Sport, for saving some weight, but obviously also giving it more leaning angle. So, the problem is real, but can it be cured?

There are not many things that can be done without removing the centre stand, but luckily they make a big difference:

1. Adjust the suspension. Factory settings are soft (actually dealer settings, IMHO), but that's why the adjustment knobs are there! Owners Manual says that at rear, and counting from from completely discharged, the std settings are 8 clicks and medium load is 35 clicks. Front fork as std is 8.5 turns open from totally closed. I weight 70 kg, and have tightened one full turn at front fork (this has hardly anything to do with the ground clearance, though) and usually ride with 12-14 clicks at rear. I've also tightened the rear rebound for one click. Like that the bike is still VERY comfortable, so I can only imagine what happens if a 100 kg (220 lbs) guy sits on the std settings bike and starts leaning... steel sparks look cool in the darkness of the night!

2. Modify the centre stand stop rubber. There are two sizes available from factory, a long one for bikes without rear panniers and a shorter one for the bikes with them. The reasoning here is that when the rear panniers are installed, the muffler needs to go lower. The centre stand stop rubber is resting at a flange on the muffler, so when the muffler drops lower, the centre stand rest-position is compensated with a shorter stop rubber. Anyway, even the shorter stop rubber is unnecessary long! First picture below shows original long one and the modified one on my Norge. If you'll click on the starting picture, you'll see an animation of the effect this mod has.

That's it. Takes five minutes (or half an hour if you set-up the suspension more meticulously) and after that you can't anymore grind the centre stand on the right hand turns, as the fairing and foot peg will ground first (pic 2 below). Left hand leaning angle is still a bit limited by the centre stand, but not much - the foot peg, muffler and gear change are getting pretty close to the ground too (pics 3 and 4 below).

I HAD A STRONGER SPRING FITTED TO REAR DAMPER FOR 2 UP AND LOADED 100 % BETTER BREVA 1100

Good info on the centre stand stop and ground clearance, thanks for the blog. I'm wondering if a shock with eye to eye length adjustment might help?

Hi there

it is my first ever "comment" about a motor bike in a blog site and please forgive me if it is not really relevant to the subject but I have just found the BREVA keyword and I have decided to post a question to anyone that has a greater (than mine) experience of riding moto guzzis.

I have the BREVA 1100 ABS 2006 model (4000 km) and I face a rather worrying and common problem. While driven and only after 10-15 mins ride the engine temperature and subsequently my legs are getting realy high. yesterday , I have driven for about 150 km and I ended up with light burns on my shin . Of course the ambient temperature was 41 C but still does this means that we do not drive in the summer ??? I am worrid for wrong settings in my moto since I face another frequent problem of the engine going off when i pull the clatch to go idle for example ona traffic light and the engines rpm are erduced. Any ideas or comments will be greatly apprecietd

I bookmarked your site.
I bought my own Norge on last Saturday.
Wonderful bike and useful tricks on your blog !!
I live between Aix and Marseille
My english is far not as good as yours, so do you have a french version of it somewhere ?


Pexi replies: Thanks Bruno, my english is far from perfect, but my french would be much, much worse; so, this kind-of-english version is the only existing one!

Nice work, though I can't get the animation to work. Might be a nice idea to repost these simulated lean pictures with you on the bike?

Pexi replies: I'm planning to do something better: I'll try to take a small in-action movie, camera attached somewhere down...

70 kilos in full monty??
All test rides I read also complained on the much too soft rear shock - maybe a change to something more sporty and maybe just a few centimeters longer would be a tip for 100 kilo+ -rider. ;-)
