cabby Posted February 9, 2012 Report Share Posted February 9, 2012 A rough guesstimate is all I'm looking for. Don't ever want to find out the hard way, but say trail riding on you're every day trials bike, be it 125/250/300, how many miles would/should I expect ??

grahamjayzee Posted February 9, 2012 Report Share Posted February 9, 2012 Absolutely no idea, but in rough maths terms, my 290 evo holds about 3 litres or thereabouts, which is a bit over half a gallon. A 250 aprilia 2-stroke road bike does about 35 mpg. Assume similar for a trialie (it's got a gentler tune, but lower gearing and higher likely losses). On the back of that, if you've ridden 15 miles, I'd be looking for a petrol station! Quote Link to comment Share on other sites More sharing options...
totalshell Posted February 9, 2012 Report Share Posted February 9, 2012 my villers pre65 does 19 miles not 21 on a ty80 tank full Quote Link to comment Share on other sites More sharing options...
sting32 Posted February 9, 2012 Report Share Posted February 9, 2012 A rough guesstimate is all I'm looking for. Don't ever want to find out the hard way, but say trail riding on you're every day trials bike, be it 125/250/300, how many miles would/should I expect ?? This is SOOO hard to guess, really. MANY things complicate it. rider size (weight), are you riding sections as you travel down the road, which bike you are on, how fast you going/gear your in, terrain/hills etc, tire pressures... My 300 pro, gets bad "hourage" note I say hour instead of mileage/kilometer'dge. I know a buddy rode a 08 280 on a 25 mile loop, at the ute cup, missed a turn on lap one, thinks it cost him a mile, he had to push the bike that mile to the pits I think he said... Problem is for that calculation, he carried 1 - 20 oz bottle of fuel and added it to the bike somewhere in the loop. my 300 runs out quicker, friend on his 250 had plenty of fuel left over without the spare fuel. Id say fill some (at least 2) pop bottles with fuel, tape to fenders with duct tape, maybe an extra in butt pack, and go on a test run, until you run out. hopefully in a big circle type path around camp, so you can cheat the mileage back to camp when you do run out... Then measure time (if you dont have a speedo especially) dump the bottles into tank and head back... should give you some idea. I can figure about 2.5 hours of riding an event, for a tank of fuel in the '08, '10, or '12 300 pro... definitely not racing down any trails while doing this though for those 2 hours, but our trials area isnt that big, so speed isnt needed... My favorite disclaimer, "Your Mileage May Vary", seems pretty much spot-on for this post... Quote Link to comment Share on other sites More sharing options...
ishy Posted February 9, 2012 Report Share Posted February 9, 2012 I was setting out a trial and wanted the event to be the longest loop inc sections I could get out of a modern day bike on one tank of gas, app 3 ltr the number I came up with was 16 mi, all off road.

djdenzil Posted February 9, 2012 Report Share Posted February 9, 2012 Longest section between fuel stops in Scott trial is approximately 15 miles and thats gunning for it. I cast my mind back to 2005 when I ran out of fuel on the Grouse Moor !!! Quote Link to comment Share on other sites More sharing options...

That's a fair indication, it would be on a gasser 125, probably a bit of road work here and there to get where I want to go then just play about. It has a speedo/clock, so I really should check it first before I go, canny really be ersed carrying spare fuel when just out for a fanny about Quote Link to comment Share on other sites More sharing options...
greg Posted February 9, 2012 Report Share Posted February 9, 2012 we always went with riding time, (i know thats not the question) but approx 3 hrs on a gasser. Quote Link to comment Share on other sites More sharing options...

Tha seems reasonable yet optimum depending on the route and speeds. I would back that off to around 12 to be on the safe side. Quote Link to comment Share on other sites More sharing options...
toothandnail Posted February 11, 2012 Report Share Posted February 11, 2012 My old 300 pro , 2.5hr . 280pro , 2.75+. My SIL's 280 sherco 3-3.25. I always told them I got worse mileage because I climbed hills while they sat at the bottom and watched. Quote Link to comment Share on other sites More sharing options...
nzralphy Posted February 11, 2012 Report Share Posted February 11, 2012 2.2l x 10 or 11 km/l for the Rev4 Quote Link to comment Share on other sites More sharing options...
pindie Posted February 13, 2012 Report Share Posted February 13, 2012 (edited) 2-3 hrs on my 07 Rev3 200. Two hours if trail style riding, easy three if just mincing around doing sections etc. My Beta also has a minor fuel dribble issue which is common. It has also had the "fix" done to stop this but is only a tiny dribble and not constant. Edited February 13, 2012 by pindie Quote Link to comment Share on other sites More sharing options...
sweetgas Posted February 14, 2012 Report Share Posted February 14, 2012 (edited) I did an 80 mile ride (completely flat boring ride) with an average speed of around 45 mph on a 01 Montesa 315r. That was all on one tank plus I had a 32oz bottle of extra gas with me(I don't remember for sure if I had to use it). It's a 2 liter tank? plus maybe about another liter. So that's what about 100 miles per gallon if you are cruising. Edited February 14, 2012 by sweetgas Quote Link to comment Share on other sites More sharing options...
