[ Ссылка ] Beta main bearing failures are now a significant issue on 2018, 2019 and 2020 Beta two strokes. See this vid: [ Ссылка ] When I talk about known issues on any bike, there are always guys who freak out and say that bike sounds like a pile of shit, no way I'm buying that! Well, don't watch the Beta known issues and common problems review vid if you are a panic merchant. You can make a comprehensive list of small issues with any brand like Beta. Like any brand, the Italian bikes have their niggling little faults and I covered these way back in a 2015 Beta enduro review. The good news? They have fixed quite a few. The bad news? There are a few things they keep ignoring... and some new issues with bikes the Beta Xtrainer, RR300 and RR390.
Let's start with the good news. The mudflap for the rear shock used to slowly wear away the swingarm, now it's reshaped to avoid this. If you have an earlier model just trim it to suit.
There were occasional false neutrals between some gears, a new gear selector on 2018 models has fixed this. Check our Beta reviews for more info.
Beta plastics were very prone to cracking instead of bending in even small accidents or just leaning your fenders against a tree. It's early days, but our experience with the 2018 models suggests they finally got around to using the nice flexible materials everyone else uses.
see ben's footage GH010707 ben crash stack jump backflip!! and my comments too.
After several years of riders saying Beta enduro seats feel like slabs of concrete, the 2018 models finally have a softer foam.... good news if you do like to sit a lot on bikes like the Beta 2018 RR300 or RR250.

One area we felt Beta let themselves down with Beta known issues and common problems was the heavy clutch. It wasn't bad compared to say cable clutches, but by European standards it wasn't good. The 2018 model is a big improvement. We've done a vid on clutch mods if you have an earlier model.
Okay. So are the Beta 2018 known issues and common problems? This includes the RR350, RR390, RR430 and RR480 and two stroke models too.
Europeans could still learn a lot from the Japanese about good electrics. It's a good idea to remove your headlight and fuel tank then use a pile of zip ties to get your wiring loom neat and not rubbing on anything. There is a critical electrical connection which is easily corroded and can shut down the oil injection system. Apparently it's been fixed for 2018, but some 2017 and all earlier models had the capacitor and diode block mounted upside down allowing water to enter heat shrink. The wires going into the magneto can be snagged by sticks when riding. On 2018 models these are secured better but still it can still happen.
Also the positive wire from starter to the solenoid runs over the frame backbone above the rear shock. Reroute under the backbone to avoid the tank rubbing the wire... some dealers fix this in pre-delivery.
More 2018 Beta known issues and common problems? The four stroke model RR350, RR390, RR430 and RR480 still use plastic cogs for the oil pump. These need to be replaced every 100 hours but most riders agree it would just be easier to make these steel. You can buy aftermarket steel cogs from Boano in Italy.
The standard coolant has too much glyco-*
The two stroke oil injection system works great for most riders, however there's a small but noticeable number of issues with bikes running too rich and fouling plugs. This is because the system defaults to something around 20:1 to avoid any engine seizures but of course it can foul plugs. Apparently the majority of cases are debris left in the system at the factory and a bit of carb cleaner will fix it. But if you can get some compressed air through it will be even better. Remember to always top up your oil. If your system stuffs up and defaults to the very rich mix it could be possible to drain your oil tank on a long ride if it wasn't full. Some riders are simply removing the system with parts from Beta that cost around $70.
Text: Debris sometimes gets caught
internally in the two ball valves of the
internal solenoid during manufacturing,
resulting in over oiling.
A small but persistent Beta known issue and common problem is that pointy-ended sidestand that just sinks into soft ground. The crazy thing is the 2012 sidestand base was double the size and worked great. Why did Beta go back to the chopstick design. Who knows. A very simple fix but Beta has been ignoring complaints for years now.
