Griso Mods for the track

So I've done a few trackdays and I'm hooked! A track bike seemed like the next logical step, but after seeing this video I've begun toying with the idea of making my Griso more track-worthy.


After watching that I figured if I was going to spend money on a track toy I might as well spend it in a way that improves my awesome street bike. Regardless of my bike I'm not going to set the track on fire, and if I'm going to be getting passed I'd rather get passed while on a Guzzi! At least then I'll look good while its happening!

A new, ride height adjustable, shock seems like the first mod I should make. The biggest issue on the Griso is left-side ground clearance (obviously the biggest issue at a track day is my riding skill, but we're talking mods here). The side stand drags and impedes lean. The stock shock's abilities in general are not too hot either, it doesn't seem to be using all its advertised height and can bottom over bumps. I weigh 155 lbs so it isn't me.

Any suggestions on how to get a semi-touring bike more track-capable that don't involve a track bike?

No advice here but that would be nice to see. I know that Goozie has tracked his bike (centauro i believe) PM him and he may have some words of wisdom. i miss the v7.

I would also factor in the cost of laying dOwn that griso vs the cost of a dedicated track bike.

Was like that with my Zx14 when I first started track riding...but then came to the realization that it wasnt the right tool for the job. I didnt want to destroy my street bike....so I ended up buying a zx6r....

Honestly, any suspension adjustment that's going to make it a better track bike is going to make it a kidney-bruiser on the street. I'd get a dedicated track .

The suspension is my biggest concern. I'm hoping that a decent shock will allow for a compromise between street and track. Again, I'm not looking to set lap records, just make the bike a bit more competent on the track. Is such a shock a pipe dream?

Those big jugs would be the first thing to touch down in a crash and the head cover is pretty cheap, less than $300 OEM (knock on wood). Built in crash guards!

I have seen MV's, Ducatis, Aprilia's you name it at the track. True one of those bikes goes down it is not cheap. Check your insurance for coverage.

A better shock will help control the tear tire better, BUT the settings necessary to control a tire at trackday speeds make riding it on the street like riding a hardtail. Some people will tell you they "don't notice it." Those same people will probably tell you their supersport is comfortable.


Now you could readjust the shock every time you go track and back, but at what point does it just become too much hassle? You're going to spend $1000-$1500 on a good shock, have to fiddle with it twice every time you go to the track, and for $1000 more, you could just have an SV650.

Thanks! At least now I'll be informed and making a poor decision if I decide to stick with the Griso.

What he said is not entirely true.
Just because you have your suspension set up for the track doesn't mean thatyour bike will feel like a hard tail. That's a little exaggerated.
The stiffness of the suspension might be more noticeable on a supersport bike but even then it's not as bad as all that.
Starting off with a bike like an MG it won't even be close to that bad. You will probably wind up with a bike that has taut but compliant suspension that will make your bike more competent on the street and still feel great.

IMHO, suspension is the first place to start. Most bikes will benefit from suspension upgrades even if they were only used on the street. Once you throw track riding into the mix, it makes sense that suspension will be a big improvement.

Talk to Patrick at Motorcycles Unlimited. He will steer you in the right direction.

If you think you're hooked now, wait a few more trackdays. Your skill/desire for speed and fun will likely outpace your griso's limits. But this is America! So do what your heart tells you, after consulting your brain.

I still haven't made any upgrades but I'm thinking suspension upgrades are in the cards regardless of whether I go with a track-bike later. Here are some videos of a tractor on the track.

Just be prepared to see your street bike destroyed. Not saying it will happen, but it doesn't take a high speed crash to bend forks, subframe, instrument cluster, etc (talking from experience here). Just the right bounce leaving the pavement over a curbing at 40 mph can send it flipping over. If you do have insurance that will cover track riding, it doesn't take a whole lot to total a motorcycle so you could end up paying to fix it anyway.

So in summary, I'm not saying "don't do it", but basically after you've done a couple of track days, don't ride anything on the track that you don't want to lose. Because everybody says they'll take it easy at first, even those with race numbers on their motorcycles now.

The tech and mods on that guzzi are awesome. The styling, not so much.

I dropped the bike off for new fork internals and a new shock today. The next week and a half cannot pass fast enough!

The fork and shock work was money well spent!

The shock changed the geometry a smidge, adding height to the rear. This not only aided turn in slightly, but it also gave me a bit more lean (particularly on the left side, where my kickstand was dragging). The sliver of chicken strips on my front tire are now history.

Even though the shock is firm, it actually handles bumps better than stock. I'm not sure if this is due to better damping, but it is a huge improvement.

The forks needed a revalve only, the stock springs were apparently right for me already. Control under braking is much improved, and I'm no longer getting any head-shake (pretty surprising to begin with on such a long, raked-out bike).

At the track the result was more confidence.

On the street the result was an improvement as well. The new suspension was tested over the worst bumps San Antonio has to offer, and it is far from unbearable.

All in all a worthy upgrade.
