The Big Three: 300cc Enduro Bikes at John Lee
Three 300cc Enduro Bikes at John Lee Motorcycles
As an official GasGas and Beta dealer, John Lee Motorcycles has the 300cc two-stroke enduro class properly covered — from the Austrian-built GasGas platform to Beta's Italian-built RR. The 300cc class is where two-stroke enduro really hits its sweet spot: enough torque to pull you up anything technical, light enough to throw around all day, and with the kind of broad, manageable power that suits everyone from clubman trail riders to extreme enduro racers. Here are three of the best 300cc enduros currently in stock.
GASGAS EC 300 2026 — £9,349
The EC 300 is the bike most riders mean when they talk about a "300 enduro" — a 300cc two-stroke built around the kind of broad, manageable power that makes long days in the trees genuinely enjoyable. It's the biggest two-stroke in GasGas's EC range, and the 2026 model carries over the platform updates that put the EC line on par with its KTM and Husqvarna sister bikes: WP XACT suspension, hydraulic clutch, traction control modes, and the option to flick between two distinct ignition maps on the fly. If you ride hard enduro, extreme events or just demanding trails, this is the GasGas to buy.
Beta RR 300 2T X-PRO 2026 — £8,395
The X-PRO sits as the standard-spec model in Beta's RR 300 line and it's arguably the best-value 300cc enduro on the UK market right now. Beta's 300cc two-stroke has a reputation for the broadest, most usable powerband in the class — less hit, more drive — and the X-PRO trim keeps things straightforward with proven components throughout. For trail riders, clubman enduro and anyone stepping up from a 250, this is a hugely capable bike at a price that's nearly £1,000 less than the headline competition. Italian-built, fitted with a counterbalanced engine, and ready to ride.
Beta RR 300 2T Racing 2026 — £9,095
Step up to the Racing and you get the full factory-flavour spec: upgraded KYB suspension, machined triple clamps, a Race-spec seat, and the red/blue colourway that's become a Beta calling card. The 300cc two-stroke motor underneath is the same proven platform as the X-PRO, but the Racing is where Beta loads in the components that experienced riders and serious clubman racers will actually appreciate. If you're riding hard enduro events or just want the top-spec version of one of the best 300 enduros on the market, this is it.
Bottom line: Whether your loyalty lies with GasGas or Beta, the 300cc two-stroke enduro class is alive and well — and all three of these bikes are in stock at John Lee Motorcycles. Browse the full GasGas and Beta ranges or get in touch to arrange a viewing.
