Four-stroke of the Future
By TMX Archives on 8th Jun 07
THE trials world has been waiting for a 125 Montesa/ Honda for several years now - and the Italian Future Racing Team - which of course sponsors James Dabill on a super-duper 300 model - has beaten the factory to it! T+MX is proud to present Britain's FIRST test of the Future Montesa 125 4RT. WOODY HOLE landed the plum job of visiting the French World Championship round and landing a surprise ride on the unique eighth-litre baby.
Says Woody: I had just jumped off the Future TRW 300 model (previouslytested earlier in the year for T+MX) which I blagged another quick rideon before grabbing the 125. I just wanted a quick update (more on thatsome other time) and my first job was actually picking-out the 125.There was a big line-up of about a dozen 4RTs outside the impressiveFuture TRW artic in the paddock in France and the only externaldifference - that I could spot - was the little 125 sticker on theside! That apart, the 125 is identical to the 250.
And starting it up I couldn't tell a lot of difference either! Sure,there isn't as much compression as on the 250 and starting the 125 wasso easy - and the sound wasn't a giveaway either, it just sounded likeany other 4RT.
So, off we go to the testing ground, up through the gears noproblem. In amongst the rocks it wasn't long before I realised thatthis is a fantastic little engine. Being honest, I wasn't expectingmuch in the way of power, I thought it would be as flat as a pancake,so this was a real eye-opener.
Like all 125s, bottom is the obvious gear, but second really was agenuine option. I found some really steep, twisty loose climbs and Icould tease it up these in second gear easily. Even more impressive, Icould also tackle some pretty impressive rock steps from the usual zerorun-up - in second. I couldn't believe it.
Thinking about it, this would make an ideal bike for the Scottish Six Days, just the right power for many riders.
Being based on a much bigger bike, stresses on the bottom-end areminimal and the clutch is going to handle 125 power like nothing. Thisengine is capable of running as a power-up full 300 so a 125 is abreeze. Surprisingly, the engine produces plenty of bottom-end power sothe clutch doesn't even get a hard time.
And when it revs it really does rev, and it makes a bit of noise about it so you get quite a buzz.
Now, you have to remember that I am definitely not Youth weight - which brings me to an important point.
We all know that with all the two-stroke trials bikes, the 125versions have that magic quality that makes them feel like they weighabout half as much as the 250 version. The actual weight is identicalbut due to the laws of physics and mechanics and stuff, something magichappens and they feel as if they weigh nothing.
For some reason, which must have something to do with thefour-stroke cycle, this is not the case with the Montesa. The 125 feelsvirtually identical to the 250. It doesn't require any extra physicaleffort but what I am saying is while the bike will be fine for theolder and bigger lads, the less physical may find the extra 'weight'-or at least the feeling of weight - a handful. This is something thatthey will have to find out for themselves.
All I can say is that the Future125 was a total revelation. There'sobviously a hell of a lot of work involved in down-sizing the 4RT andthe price will reflect this in any production versions - but I wouldsay that you will definitely get what you pay for...
THE 64,000 dollar question is, ''Exactly how has Future transformedthe 250 4RT into a stonking little 125cc mount.'' The answer is asurprise. Sure, the bore has been reduced, but only down from 76.5 to68mm. The shock is the new stroke of just 34.4mm. Check this outagainst the 250 4RT stroke of 54.2mm and it makes you sit back andwhistle through your teeth. Future has opted for a super short strokeand you can't argue against what they have produced. The proof of thepudding is in the eating and the performance - as Woody Hole discovered- is a real eye-opener....
