I do not like the digital crap up on the dash, but most do for you see I am an old man so digital & I do not jive. My problem, but just two buttons to control two trip meters, MPH/KPH, chaning temp gauge to Celcius & such does bug be. THOUGH it is going to become more popular.
Both are the same. Both bikes are very similiar though the 954 has more torque, rider is positioned up front an inch or more, clip-ons down around an inch or more, a bit more visor on the fairing, brake pads are a bit larger & the rad is dramatically larger. Just a few points on the 954 Vs the 929. One draw-back on the 954 is that larger rad has to send the heat somewhere & it is to the underside of the upper parts of my two legs. Cannot possibly ride the 954 without questioning if said parts are not being slowly roasted. Still one should not be riding with just jeans.
A lot of rattle from the upper parts of the 929, but you soon get use to it. Some claim the saddle on both is a "plank" though I find them comfortable & remember when riding is there I ride basically every darn day of the week, bar Sunday where I put my time into running the h/gun range, & that is 5 to 8 hrs each run.
Not necessarily a Honda man & have had more Yamaha then Honda bikes. Have not riden the Yamaha R1 for it would mean bumming a bike from a shop or riding someone elses & in my mind riding someone elses bike is a bi3e NO NO.
If you do get a 929 or 954 then get a decent rotary steering head be it a Scotts or GPR & not some of the cheaper piston ones. Also frame savers & yes I ride the bikes with stock exhaust system & only other changes are changing front brake lines to Kevlar lines & that comes from past experience in road racing. I just like best set of anchors possible.
Remember all the others on the road are crazy & out to kill you.
