2017 BETA 250 RR AND 300 RR
FULL TEST
P80
The 250 and 300 RR are off-road
bikes, designed and set up for the
average off-road rider and are not
green sticker machines for those liv-
ing in California, and they also don't
come with spark arrestors. How-
ever, we remedied that by quickly
installing S/A FMF mufflers, making
them legal to ride on public lands for
our testing.
About The Bikes
For 2017 Beta made only subtle
changes to the 250/300 RR, which
was an already great package. The
Sachs fork is 5mm longer to provide
a bit more wheel travel, and inside,
a higher grade fork oil reduces
heat build up and reduces friction.
The Sachs shock has a new high/
low speed adjustment system that
Beta tells us is more sensitive when
changing settings.
The triple clamps have been
updated and are now lighter while
providing more rigidity.
The proven two-stroke engine
remains the same, featuring a six-
speed transmission, electric start
with a kick-start backup, an adjust-
able power valve, a smooth-working
hydraulic clutch and a dual-map
ignition switch. The only differ-
ence between the 250RR and the
300RR comes in the size of piston
and cylinder bore, 293.1cc versus
249cc. Stroke is the same at 72mm.
The sliver Excel rims with black
spokes not only look cool, but are
now lighter.
A new computer shows speed,
average and maximum speeds
and the ability to adjust mileage in
smaller increments. It also has warn-
ing lights in regards to the level of
the premix oil.
The RR's also have an Allen
wrench and 8mm socket hidden
under the seat that help the rider
gain access to a tool stash area be-
hind the left side panel and airbox.
That area can hold tools or a 21-inch
regular tube. Pretty cool.
Back for 2017 on the RR two-
stroke models is Beta's Electronic
Oil Injection system. The two-stroke
oil is stored in a tank under the seat
(the seat is easy to remove with
just a push of a button) and holds
12 ounces of oil. The oil-injection is
managed by an ECU, which feeds
a precise amount of oil into the
system based on rpm and engine
load, measured through the throttle
position system (TPS). The ratio
varies from 32:1 to 100:1, depending
on the demands of the rider and the
(Above) The 250 and 300 share
the same engine, only the bore
size is different. Even the stroke
is the same. (Right) Both the 250
and 300 RR are ideal for technical
trails. The 250 RR (shown) has a
lighter feel than the 300.
