I’ve been sticking mostly to tarmac since blowing out my knee a few years ago but after major surgery and a few years of rehab, I have gotten it to the point where it is as good as it will get and, with the aid of a custom made unloading knee brace, I’m finally back in the dirt – on the perfect bike for the job, a 2019 Yamaha WR250R. The WR R is an easy going LAMS approved trail bike perfect for me… Check out the full review we did on the WR R here and also check out this, my first video update on the bike. I have it for six months and there are a few mod’s planned. First off, better tyres… Stay tuned! Pics: Heather Ware.

Jeff is back in the dirt and looking forward to easing into it on the WR250R.

WR250R Tech Details

Engine
Starting at the down draft intake for the fuel injection system before leading into a four valve head with titanium inlet valve, the WR250R has the same bore and stroke of 77 X 53.6mm as the race bike and is well proven. There is an air control valve in the intake and an EXUP valve in the exhaust tucked just behind the right frame rail and operated via a remote motor. Also located here is the Lambda sensor to measure the air to fuel ratio so that the ECU can make fueling changes as required.

Direct ignition coils eliminate the need for coil packs mounted to the frame and the coil driver is built into the spark plug lead and just pushes onto the spark plug. Running a lowish compression ratio also means you can run a lesser grade of fuel without fear of detonation. The kick start has been removed and the compact electric starter brings the WR250R to life. A six speed gearbox has good all-round ratios and overall the engine is very smooth and easy to use.

Bike Review 2016 Yamaha WR250R (11)Chassis
A three-section semi-double cradle frame has been used and this means that the backbone is an aluminium main frame with a steel engine cradle and a steel sub-frame. The chassis is compact and out on the trail very stable with 300mm of ground clearance. The front wheel is a 21in enduro wheel, while the rear is an 18in, giving you a huge choice of rubber to choose from.
Both forks and shock have full adjustment via compression, rebound and spring preload. They also both have 270mm of travel for a plush ride. As mentioned above they do not like to take big hits but for everything else they are fine. Front and rear brakes are both Nissan items providing ample feel, while the front would ideally offer more power.

The seat is wide and comfortable and would be easy to spend a day in the saddle on, while the digital speedo is easy to read and use. Being a road/trail bike there is a keyed ignition switch. Switch gear is all pretty standard fare and works as it should.
