Specials!
The Kawasaki KLR650 has a proven track history, having only a few changes since 1986. We're not sure why they aren't more popular really, they are quite cost effective and comfy. While a Suzuki DR650 can be bought cheaper, most people then have to go get a bunch of aftermarket bits to make it more useful, but not so with the KLR. The headlight is properly bright (no DR candlelight). There's a windscreen already there, and being factory, it actually works! Quietly too, no squeaks or wind-noise, without buffeting a peaked helmet. Nice big fuel tank. Good handguards too. Blinkers that drivers can see. It's all very well thought out and works harmoniously, not just thrown together.
So if you want a budget adventure bike that you don't have to cobble together like a meccano set, we are offering special prices for the following package only:


KLR650 Upgrade. New Fork Springs, V4s Valves in Forks, Damper Rod Modifications. Revalved Stock KYB Shock, New Shock Spring.

Suspension Only $850
Ride In & Ride Out $950

Forks
Up to 2007, the forks were a very small 38mm diameter, and 2008 onwards saw an increase to 41mm. Both were Damper Rod Forks, which don't give any speed-sensitive damping, unlike more modern cartridge fork designs. One of the simplest solutions, without resorting to the huge cost and difficulty of grafting in cartridge forks, is to install what Kawasaki themselves used to call "Travel Control Valves" (they have also been called Gold Valves, PD Valves, Emulator Valves and a bunch of other stuff). We call them V4S Valves, and they help give damper rod forks some much needed speed sensitive damping.
  • Fork Revalve & Service with V4S Valves. Its not just any old service; the welding, the machining and the Teknik designed travel control valve system give huge benefits over the stock parts. It means that the front end feels less busy, and rather than dancing all over the place, feels stable and planted. After a long day in the saddle, your arms won't feel like jelly. Depending on your weight, and how much gear you carry, you may well need to change your fork springs to suit too. You can find the fork spring rate you need HERE.
Shock
From the factory, the 40mm KYB Shock is lightly damped and under-sprung, making for some trouble if you are heavy or intend to carry any gear.
  • Stock Shock Service & Revalve. While it doesn't sound as amazing as an adjustable replacement coilover shock, once we have gone through your old KYB shock with new parts and custom set the valving to suit you and your riding, the end result is a spectacular improvement for a much cheaper price. You will want a stiffer rear spring too; find the perfect shock spring rate HERE.
Extra Options
  • Accessories. Racks and other accessories can be found at Adventure Moto in Sydney NSW.
  • Large Fuel Tanks. While quite a popular mod, we don't actually recommend them. One, the stock tank is already quite large, about 300kms large. Two, it's just more weight over the front and over those poor old damper rod forks. It reduces the handling further, increasing understeer. Three, do you really want to adventure in so many places where there isn't a petrol station for more than 300kms? For most people it's overkill and your money is better spent elsewhere, in our humble opinion.
  • Tyre Selection. We like the Dunlop 952F front as the 650 does not give a lot of feel from the front, regardless of the fork setting. Dunlop D606 is the best all round rear. The Michelin HP4 is also a great front but not road legal, the T63 is a great rear choice too.
