Fixed Pants™ Posted February 13, 2007 Report Share Posted February 13, 2007 Pete Wright.Only joking Pete, i love you.Ot Pi's dad made him one from a BMX, as said. He made it because he wanted his son to ride trials but somewhere a long the line someone didn't want to do it on a moto trials bike. I think.

mikey23 Posted February 13, 2007 Report Share Posted February 13, 2007 For those of who are interestecd in the history of moto trials, have a read...Trials bikes are specialized off-road machines. This wasn’t always the case; when trials started in Scotland before 1910, riders used regular machines, usually the common four-stroke singles. There wasn’t the degree of specialization of motorcycles that we have now. The bikes then were suited to the trials events of the day-, which were basically hillclimbs-with lots of low-end power and large flywheels. The flywheels and soft tuning allowed for plenty of ‘plonking’ power to creep over and around obstacles, and the four stroke bikes had plenty of traction. As trials became more specialized, the bikes improved along with the events. Or perhaps the events became more difficult as bikes improved. Whichever, a milestone in the evolution of trials machinery was Sammy Miller’s 1960’s factory Ariel HT5, known as ‘GOV132’ after its license plate number. Sammy lightened the bike and changed the steering head angle to get quicker steering. The result was a bike that went over obstacles better and could do tighter turns. Miller’s success with the Ariel was noticed by his competitors and by the makers of competing machinery, including AJS. Soon others were shaving weight off their bikes. Sammy was hired by the Spanish company Bultaco in the mid-60s. Bultaco was successful making lightweight two-stroke machines for street and road racing and wanted to move into trials. The modern two-stroke trials bike was born from Sammy Miller’s work on the Bultaco. Other Spanish manufacturers, always competitive with Bultaco, started working on trials bikes of their own. Soon the trials loops of the world were filled with Bultacos, Montesas and Ossas, all making rattly two-stroke sounds and castor-oil smoke while doing obstacles that riders of the heavier four-stroke machines could only dream about. Mick Andrews, another British trials legend, helped develop the Ossa. Trials boomed in many countries, especially the United States. Motorcycle magazine editors predicted that trials would be "more popular than motocross." In 1973, expecting the trials boom to hit any moment, Honda introduced the first Japanese production trials bike, the four-stroke TL125. Yamaha, Suzuki and Kawasaki followed a year later, and a Honda TL250 arrived in 1975. The Japanese bikes did not handle quite as well as the Spanish bikes, but were reliable and could be made to handle well enough. The Japanese makers followed the Spanish company’s tracks and hired some of the big names in trials to help develop their bikes. Mick Andrews went to Yamaha and worked with them for many years. Honda hired Miller away from Bultaco and he helped them develop their TL250, first by making a lighter frame with more ground clearance, then with advice on the factory’s expensive magnesium and titanium RTL competition models. In 1979 and 1980 the Spanish companies suffered from labor strikes and walkouts. The USA trials boom had never come and Spain was beset with economic problems. The championship Bultaco factory team with newly-crowned World Champion American Bernie Schreiber was forced to disband mid-season, with each rider finding a home on a different make. The reign of the Spanish manufacturers ended and some Italian makes picked up the slack. SWM, Italjet and Fantic started volume production and started supporting riders, and winning, in the early 80s. Honda went to Europe with even more advanced four-strokes to contest the world rounds and won two championships under Eddie Lejune. At this time, the bikes were of the same basic design that Bultaco pioneered in the late 60s, albeit refined with slightly lighter weight, better power and slightly longer travel suspension. But the huge suspension revolution that had occurred with Motorcross machines in the mid-70s had little effect on trials machinery. That changed in 1984 when Yamaha introduced the new monoshock TY250. Having no parts in common with the old 1974-design TY, the new TY’s centrally mounted shock, low seat and longer travel suspension revolutionized trials bike design. The other manufacturers leapt to follow suit, with other monoshock models coming out a year later. At this point, the major manufacturers were Yamaha, sole Spanish survivor Montesa, Italians Beta and Fantic (SWM and Italjet having ended their fling with trials). Yamaha didn’t sponsor top riders but their new TY Monoshock bikes were very successful in club events. In the last decade, Beta and the Spanish Gas-Gas Company have pushed trials bike design forward, with disc brakes, water cooling and narrow perimeter-type frames. The modern ‘stop and go’ riding style pioneered by Schreiber, LeJune and others, where riders hop the bike to get into position then drop the clutch to launch themselves over the next obstacle, affected trials bike design. Top riders demanded quicker revving engines to rocket them over larger obstacles with less run-up than before. What the World Round riders use one year becomes the production bike the next. Modern trials bike design has stabilized for the moment. A modern trials bike has a very low seat, to allow the rider to crouch low on the bike or let the bike come up farther to him when cresting a big step. Suspension travel is usually around 7 inches in the front and 6 in the rear. Damping is light, biased towards letting the bike rebound on it’s springs to make hopping the bike easier. The engines are all water-cooled two-strokes with reed-valve induction. Engine response is much quicker than the old Bultacos, making it possible for a rider to jump up a step with little or no run-up. Tires are sticky-compound tubeless radials on the rear, and sticky tube-type bias-ply on the front. Typical tire pressures are 4 psi rear and 6 in the front. The radial rear tires have flexible sidewalls to let the tread form itself around irregularities, increasing traction. Typical weight is around 185 pounds with all fluids and the usual 1 gallon of fuel on board. Gearboxes are usually 6 speeds, with three closely-spaced low gears to give the rider a choice of gears for sections and three higher gears for riding the loop (and roads where legal). The latest developments are hydraulic clutches and exhaust power valves. The lever effort with a hydraulic-actuated clutch is not improved over cable clutches, but the hydraulic system gives the same engagement point no matter how much the clutch plates get hot and expand. The new Fantic Section features an exhaust power valve. The valve changes the timing of the exhaust port, allowing Fantic to tune the engine for good low-end power and still let it rev more than most trials bike engines.Taken from the "History of Trials" by Eric Murray Quote Link to comment Share on other sites More sharing options...

Guest Posted February 13, 2007 Report Share Posted February 13, 2007 Yeh but that's not the whole story.In the leaps and bounds DVD there is footage from where the first bike was made, there are even protoype bike's there from back in the day, some of the first ever factory produced bikes, which were not monty. A really interesting part of the film and definately worth watching if you want to know anything about history of trials. Quote Link to comment Share on other sites More sharing options...

montyrider07 Posted February 14, 2007 Report Share Posted February 14, 2007 (edited) the origional picture is on monty site, www.monty.es and i do believe ot pi's dad invented trials, after wondering if it would be as easy to do it on a push bike than a motor bikeEdit= click on the link at the top of monty homepage, 'about monty' Edited February 14, 2007 by montyrider07 Quote Link to comment Share on other sites More sharing options...
Guest Posted February 14, 2007 Report Share Posted February 14, 2007 Like I said above, those are not the first trials bikes ever made. There were proto's made out of girls bikes (cos they had no top tube a very low one could be welded in) The first production bikes were known as Montesitas but there were prototype's before these came about, and funnily enough the two spanish guy's who are there don't mention Pere Pi once.

monty boi Posted February 14, 2007 Report Share Posted February 14, 2007 This is the first serial bike ever built . This bike was made in 1978 by Pere Pí ( Monty Chief manager ). Model´s name is " Montesita T- 05 " and is the little sister of the world famous T-15. This bike is from Ot Pí´s collection. Adam. Quote Link to comment Share on other sites More sharing options...
Guest Posted February 14, 2007 Report Share Posted February 14, 2007 (edited) 1977-1978Modified 'BH bicycles' which were 'street' bikes. Outside the shop where the first protos were made.The man who made the first prototypes.more to comeOh my goodness, not a monty!Then they realise it's practically the same as the megamo....

Greetings Posted February 14, 2007 Report Share Posted February 14, 2007 As far as I remember, motorbike trials was under strong influence of bike trials at one stage. In L&B they talk about a bt rider who went over to motorbike trials and completely changed the sport introducing static techniques which he had learned while riding bt.

gianttrials Posted February 14, 2007 Report Share Posted February 14, 2007 It's definetly worth watching leaps and bounds if you can, because that goes in-depth about the history of biketrial, although some very prominent figures in the sport have been left out, for example, the marts, libor karas, petr kraus, Jeff Lenosky, etc. Well worth the money it costs.

sam-cahill Posted February 14, 2007 Report Share Posted February 14, 2007 Apparently Ot Pi's dad made the first pedal Trials bike out of a BMX..... Not sure about motorcycle trials though...Anyone know? JoeYep i read that on the monty website.Apparantly ot pi's dad work for montessa trials and ot pi wasnt realy into the motorbike trials so asked his dad if he could have a peddle one so ot pi's dad looked around but found that they didnt make them so he turned ot pi's bmx into one with a bashplate and stuff on it.Then one day when they were watching a motorbike trials comp ot pi went on this bike that his dad had made and all the children there loved it and wanted one so thats were ot pi's dad fort of making loads of them.So ot pi's dad went to the boss of montessa and asked if they could start making them the boss sead yes but he had to design and find workers and stuff like that.They called them the mini montessa.
