  1. Montesa 4Rt for newbie

    How about a nice two stroke Honda!
  2. Sherco bikes of the last 10 years;

    Neither. A three year old bike is governed a lot by its use and its maintenance and even the number of owners sometimes. I have personally had several Shercos although I avoided the back tank models. My 2016 Scorpa is made in the same factory with the same components and is first class. Personally all my (2003, 05 and 07 all new) Shercos were fine construction wise, with no issues. A 2015 Sherco is the first year of the 'normal' design again. It has the slightly irritating but normal Gasser style air filter fixing screw (tail on a donkey) now thankfully changed on the latest bikes. I think the engines are pretty much bulletproof with a bit of normal care ie filters oils coolants etc..

    I was the 'bouncer/passenger at Gordon's first car trial at Longmoor Hampshire in about 1964 ish. I didn't know who he was, I read about trials every week in Motorcycle News but I didn't go to events so I didn't recognise him. He was just introduced as Gordon, needing a passenger. To say he was a natural is understating it! I thought 'My god this guy's so good.' At the lunch break (in the pub) I asked him his second name and it all fell into place. We came 4th overall I think.

    The front spark plug front axle rule was clearly intended to control weight distribution. I believe it can only be a 1/5th of the wheel base behind the front axle. The cars can suddenly rear up when climbing also when reversing from a climb on a steep hill when the back brakes are on. Yes the transaxle is for the same reason as is the lead in the spare tyre centre. Ballast is OK but must not be changed during the event. All cars must use the same named tyre and at each event a tyre pressure is announced. This event it was 5psi. No supercharging, so carbs or FI, the engine size being around 1500cc as in Honda or Suzuki. This trial car design is a 'Sherpa'

    Couple of photos of the trick style sporting trials cars at an event near Petersfield in Hampshire over the weekend. Like the two and three wheel variety there is a thriving 'Retro' car scene but the rules on altering original parts (think Ford 1172 side valves and BMC A series motors) are pretty strict. The latest cars (photos) have transaxle gearboxes and elaborate suspension setups, but all the cars cannot shift their engines back beyond a certain point. Also they are not allowed to fit limited slip diffs. All sporting sections are what we would call graded hills, often with many turns.
  6. YAMAHA have a new TY

    Is it single speed ?
  7. YAMAHA have a new TY

    That came out of nowhere! Looks good.
  8. 2018 Beta Evo 200 or Factory 125

    The Beta 200 is a bike which is discussed quite often on TC and at trials etc between older riders especially. In Blighty they are pretty rare. If anyone has a 'road' test a link would be appreciated. The engine of the 200 is now based on the 250 not the smaller engine so it is now considered a shade more robust. The right answer, as always, is for you to try them both. The bigger engine will surely have more torque which would be helpful, but probably not enough to pull your arms out! The 'Factory' might look a shade more 'trick.'

    Batteries need to be replaced more often than pistons and they cost a lot more... Good point, batteries are expensive I agree, but if we are talking running costs don't forget, petrol and 2 stroke mixture is I suspect is dearer than recharging the batteries, judging by what local Nissan Leaf owners tell me. So there is a balance. My main point about electric trials bikes is they are quiet and non smoky and in more densely populated areas that is a big plus, especially for regular practice.

    Sounds like the e bikes won't fry your brains or any other parts except maybe your toes! And no worse than the petrol jobs, don't think we have hydrogen or diesel ones...yet. ...from Phys.org "The intensity of magnetic fields in seven different electric cars, one hydrogen car and one petrol car were measured in order to ascertain whether they approach the recommended limiting values for human exposure. The measurements were carried out using real cars in a laboratory and during road tests. The highest values in electric cars were measured near the floor, close to the battery itself and when starting the cars. In all cases, exposure to magnetic fields is lower than 20 per cent of the limiting value recommended by the ICNIRP. Measurements taken at head-height are less than 2 per cent of the same limiting value. In the case of petrol and diesel powered cars, exposure was measured at around 10 per cent of the limiting value. In other words, there is little difference between electric cars and petrol and diesel cars." Read more at: https://phys.org/news/2014-05-danger-magnetic-fields-electric-cars.html#jCp

    Well I guess if you have a secret section in Central Park NY and live across the way up on 5th Avenue there, you can afford the bucks! OK it's for the better off rider like the Tesla Model S is to the similar sports car buyer. Although in my neck of the woods there are 4 titanium framed Vertigos sculling about and they weigh in at Uk £10,000.

    "I don't think numbers are important here" With respect, I think they are. Watts and Kilowatts in E bikes are comparable to cubic capacity in petrol engined ones and for example the Tesla cars are rated in BHP as described by Jeremy Clarkson road testing one. The Gas Gas with it's15 KW motor is going to pack a considerable punch in any language.

    The T 18 I am told by a decent rider who has tested it in Span is that the bike equates to a 200cc 2T like the Beta. I asked several times about battery longevity and that what what was said, and you get two. An experience World TC minder Brit said the Gasser was quotes 'bloody powerful' and flew out of the sections. Ok subjective but the published figures put it up with the 250 2Ts. Incidentally 15KW is capable of giving a nasty shock not to mention melting the carelessly placed screwdriver. As for claimed output no doubt they will be tested. Not all Trump tweets are rubbish by the way, some seem spot on in a rough way. The South of England is densely populated with lots of semi eco nuts and not in my backyarders, so an optional silent bike makes some sense. Other places probably not.

    Señor Nou. Speaking to the importer today who has ridden it at the factory I can confirm the T18 Mecatecno Dragonfly now has a SIX speed gearbox and the battery lasts for 4 hours. It comes supplied with two batteries. Two demo bikes will come into the UK first for possible customers try out.
