1. Gearbox and Transmission Problems

Out of several problems in Moto Guzzi Breva 750, the transmission issues are the most stubborn, frustrating, and most common problem on almost every Breva 750 ever manufactured, especially its early models. There are several issues in the transmission department of the bike.

Among certain transmission issues, the owners face the failure of components too early. The transmission hub fails because it breaks.

Similarly, issues with the clutch and cable, all affect the transmission problem, and gearbox failures make it even worse.

For the gearbox, some owners heard of noise since the gears are grinding with each other. It’s not just stopping you from the smooth transmission of power, it’s also affecting the engine’s health. A few owners even faced problems with the entire assembly.

Well, the failure of these components is always expected but not too early and especially on this massive scale. Anyways, a problem is a problem and we need a solution for that. The gearbox rattles when the engine is idle.

The best solution is to improve every step of the way you shift the gears. Always pull in the complete clutch, engage and disengage should also be complete, and you should take serious note of its maintenance. Strictly following these steps will stop this issue from happening.

If the problem is still there, fix it yourself. See if the condition is bad or not. If not, take the clutch assembly out, and get the plate out for using it on the input shaft. It will eliminate the vibration and smoothen the transmission if your clutch is the actual reason.

On the early models, however, the gearbox can be the cause since early models had issues with gear selector fork assembly. Fixing this part will require more effort and the best way is to ask a mechanic.

The clutch lever will need lubrication but the cable doesn’t need any lube. A few adjustments for the clutch cable are necessary and to replace if the clutch cable is broken.

2. Starting Issues and Failures

A common problem in touring motorcycles and no one can ever skip this. Moto Guzzi Breva 750 sometimes never starts, starts but dies stalls, and a few other related problems. They all are the same, but you need a different eye to look into each.

The Breva 750 stalls and you need to check multiple things, mainly electrical, fuel pump, and its starter. Its starter commonly fails mainly due to issues with relays.

The relays are located under the seat and they may malfunction due to cold or hot starting, moisture content, and also if the bike was sitting for weeks. In that case, just replace the starter relay and the engine must start.

They are all fixable though but it may take time and effort if you don’t know how to fix them. Also, the relays are cheap enough, and installing a new one may hardly take 15 minutes.

Must double-check the battery and connectors to the starter solenoid. A loose connection is a common cause of why the engine stalls. If that is the case, readjust them instead of replacing them.

Other than a bad starter, a gone ignition system or switch can also be a problem, if the bike is not starting at all. Check for its spark plug, see if it’s clogged, and clean if there’s a lot of carbon. Then, take a look at the ignition coil, they often fail and ultimately lead to this failure.

It may also not start, or die due to idle issues which are common in the motorcycle. There could be issues with the throttle body and transmission. The motor may also fail which could be a reason.

3. Electrical Faults and Sensors Failure

Moto Guzzi Breva 750 is an Italian motorcycle and electrical issues are pretty common in almost all Italian manufacturers, be it Ducatti or even Benelli. It’s in the Breva 750 too. Battery issues, wiring, and other electrical failures are common on this machine. 

Other than its starter, the fuse is the most vulnerable part and it fails quite often. The fuse fails due to overloading electrical components and issues with wiring. When it fails, it stops the entire electrical system of the motorcycle no matter even if your battery is fine.

The battery also fails on this machine although it’s not common which is a great thing. But, it can fail since it’s been reported several times.

Because it is an expensive fix since you need to replace the entire battery. However, it fails due to voltage issues and when there is not enough voltage, the battery either dies or quickly discharges. It may also fail due to moisture issues and especially if the connectors are rusty.

The motorcycle has several sensors that are operating to provide you with massive ease. However, they also fail and electrical failure is one of the main causes when a sensor fails. More often, the speed sensor fails on it which is linked to the wheel and ECU.

When it fails, several problems can happen including a problematic cruise control.

Normally, the quality of sensors is fine and they just malfunction due to any impact or damage through air, oil, or dust. Wiring issues and loose connections can also cause it to fail but fixing them is not a big deal. Replacing your sensors is always a choice, however.

4. Leakage and Failure of Components

The failing components problem is almost with every single motorcycle out there and with Breva 750 too. Other than the above-mentioned components that fail, there is still a bundle of other failing or malfunctioning components due to so many reasons.

The turn signals fail on this machine, mostly due to a bad bulb and it stops working. A quick and cheap fix however is just to change the bulb. Other electrical faults include a falling fuse, a dimming speedometer and vibration in it, and inaccurate fuel light due to sensor failure.

Mechanically too, there are several problems with this motorcycle. Firstly, the throttle body response gets bad due to balance issues which are common on motorcycles but it’s not an expensive problem.

Similarly, the pushrod, starter motor, and transmission components fail due to wear and tear, as well as due to not maintaining them properly.

Further, there are uncommon but major failures like problems with rings weaning out and affecting the functioning of pistons. Acceleration issues, since the bike is a touring motorcycle with not the most powerful engine, you will not get a happily fast top speed.

However, it’s enough for a touring motorcycle, but it does not compete with a sports motorcycle.

5. Fuel Injection and Suspension Problems

Breva 750 has some fuel issues, particularly with the gas tank which leaks, and the type of gas you add into it. The fuel economy might not be great, but only if you add 95 to it.

Early models had more leakage issues due to the breaking of the breather tube. However, it’s not a problem in later models. It had issues with fuel injection, but a fuel injection kit solves it mostly.

For the suspension, it leaves you too early and the suspension fork fails very soon. The best thing you can do is to upgrade its suspension if you are not a big fan of it. Additionally, install great tires so they can enhance the suspension even more.

Moto Guzzi Breva 750 User Reviews/Feedback:

“After being away from riding for about 20 years, finding a bike that simply puts a smile on your face every time you ride it is great. Moto Guzzi offers a unique brand of bike for people who want something other than the run-of-the-mill motorcycles of today. Great bike, I recommend it to everybody.” Source: Moto Guzzi Breva

“The bike is fun to ride, with smooth acceleration and shifting, only a bit of lurching/hesitation when cruising through small towns at 15 mph (too fast for 1st gear, too slow for 2nd). Handled Angeles Crest Highway in Los Angeles like a dream, it loves the twisties. The seat is comfy, even on a 3000-mile ride. My only beef is with the ‘touring screen’ for the bike. The airflow comes over the top of the screen and slams me into the top of the helmet. The buffeting is annoying after a while. And the screen isn’t adjustable. Other than that, I enjoy riding the bike.” Source: Moto Guzzi Breva
