    Hi All,

    Back in Post #30605 I posted a couple of photos of my Australasian Safari-prepped WRR. Well the rally has been run and won, 3,300km over eight days - the little WRR and I ended up finishing 22nd overall from 37 starters, and won the 250cc class. In all that racing, the only "regular" maintenance needed was one oil and filter change on Day 4, a new chain slider on Day 6 and replacement of the rear mousse tube (ran the same front and rear tyres for the whole event, although the rear could have done with replacement by Day 5). She ran like a dream, lacked power in the deep sand, and maxed out at 115kph (with 13:49 gearing) on the transport stages, but for most of the rally was able to keep pace with the faster mid-sized machines. Fuel consumption (given it was mostly sand-based terrain) was pretty high, around 6 litres per 100km at race pace, so some of the longer (260km) stages needed the fuel I kept in a 4-litre Nomad rear tank mounted on the rear guard in addition to the 14-litre Safari tank I ran.

    I took my WR250R to Broome once and it was terrible in the sand, it took so much physical strength to get it to do anything and I'd be worn out in 20-30 minutes of it and I'm at the gym 4-5 nights a week. This was its real downfall imo, thankfully there's no sand where I live now, for here it's the best bike ever imo!

    Llamaha;

    Some others like Highfive have done dyno-testing
    http://www.wrrdualsport.com/tech-guide/dynotesting, but comparison is pretty much mute unless the pipes were compared on the same bike with the same Dynamometer in similar conditions and modifications; correct?

    Dave/Sequent;

    Congratulations on your class win!

    What tires did you run and what pressure in lbs/sq in. I'm having similar problems with sand. Would you have changed to a different tire make if you knew ahead of time?

    mine was pretty much the same in deep sand, until I changed the gearing, much easier now. And by all accounts by those I ride with, I am the best by a significant margin in the sand. I am not saying that I am a great rider, just that of the guys I ride, sand is where I leave them in the dust... Single track not so much

    Hi all,

    I just tried riding a 2008 wr250r and was surprised I could just barely get the toes of both my feet down. I'm 5'8" with 30" inseam & was wondering if this sounds about right. The 2nd owner thought the bike was at stock height, but couldn't say for sure. Just eyeballing it, it appeared a little shorter than the bike I saw at the dealer.

    I have a 30" inseam, and after doing the factory lowering (threaded out the shock clevis, raised fork tubes 3/4"), I get the balls of my feet down, and if I slide forward to the lowest part of the seat, flat-foot. I also weigh 225 lbs, which compresses the suspension more than a lighter person would.

    Just noticed that I lost my right side cover sometime in the last week. :( and it was the one with my DrCool sticker on it. Now I need to figure out if I want a new colour or stay with stock blue and white.
