Less change between numbers is less change in viscosity across temp range. Hence the reason TBT etc use 2.5 exclusively in forks. For viscosity index, forks around 150 is good, and 300 plus at a minimum for shocks. Shock damping is anything from 4 to 9 times greater than fork requirements, and gets much hotter.

The adventure seeking segment has gotten a little more competitive with the launch of the Honda Africa Twin Adventure Sports ES DCT that now has to deal with the presence of the Kawasaki Versys 1000 SE LT+, BMW F 850 GS, Ducati Multistrada 950 and the soon-to-be-released Triumph Tiger 900 Rally Pro. 111 posts · Joined 2016. #7 · Apr 5, 2017. I also have a Transalp 650 in which I run in the front a TKC80 and the pressure I use in this one on tarmac is roughly the one Honda suggests, i.e. 30psi everyday and 32psi in loaded trips, and it has been fine. When I go offroad, I drop it to 22-23psi. I am planning to do exactly the same in my The Rebel 1100T is powered by a liquid-cooled 1,083cc Unicam parallel twin derived from the Honda Africa Twin. Tweaked and modified to suit the cruiser vibe, the Rebel’s engine has unique engine 1,084cc liquid-cooled Unicam® four-stroke 22.5º parallel-twin. Valve Train. SOHC; four valves per cylinder. Bore x Stroke. 92.0 mm x 81.5 mm. Compression Ratio. 10.1:1. Induction. PGM-FI electronic fuel injection w/ 46mm throttle bodies (Throttle By Wire) The Honda Africa twin can trace its DNA right back to the Paris-Dakar winning machines of the late 1980s. The XRV650, launched in 1988 was the first road-going version based on the hugely AWLftOo.
