Gas Gas = Grab Another Silencer Grief After Sale

Yes, but its oh so light.

Gas Gas = Grenades Are Specialty

Bou's Dad for sure. Ot has ridden at least one Trial on a motorcycle that I know of.

Dirt Rider article-Erzberg Trials riders 1-2, should have been a podium.

Gas Gas = Grab Another Spanner Montesa = Mon-testicle KTM = Keep the Motor Xispa = ? anyone got more ?

Well said.

Right you are, diversity is the key. Fact is that our sport has several forms now, in the past it was one Trials for all. We are all old gits, I'm just trying to stay relevant.

Perhaps you are right, you are an old git. Let the young lads enjoy modern trials and you can have a go at the Vintage scene. There is plenty for you to enjoy there. You don't see the young'uns going on about the old farts. Now back on topic, which team was it that protested against Fuji?

Good observation, its proof of how important the basics are and how little hopping and jerking matter (for the average rider), especially when its slippery

who was it that protested ?

an exhaust leak (at the cylinder) can cause a mis-fire.

Agree 100% Stoner Rocks! Fastest man on the best bike. Those slides in Catalunya were epic. Love MotoGP!

The 4RT and now Ossa, deliver the most modern technology and not a load of Hokus Pokus changes. Other than light weight the Big Two are still delivering mid 90's technology. Loads of color changes and bling. They are masters of marketing and creating the "perception of change". Granted performance and quality have improved but the latter had to consider where it was.

Yes, its an oil sump.

Costs may have been an issue. The rims are one of the most expensive single components on a trials bike.

if you think about it, this is just the rear cylinder off the Honda V4 layout

its more like 25 years. The Cota 335 had a flanged rim in 1986.

Could this be the first view of a new engine configuration for Honda singles (CRF & 4RT). True its a a long way from a trials engine but when there is a new 4RT motor could it be with the cylinder canted reward, intake in front, exhaust out the back? The new NSF250R was given its first public viewing during a special HRC presentation in the Montmelo circuit paddock earlier today. Honda gave some details about the new project, with the bike available to purchase for 23,600 Euros, while sales of the bike are estimated to commence in December. A press kit issued by Honda said: "The NSF250 engine was developed exclusively for road racing, to ensure superior quality and greater potential for commercial racing machine. With a development concept of "lightweight, compact, high output and efficiency," numerous technological advances were introduced to create an engine befitting a racing machine. "The DOHC single-cylinder 249cc engine demonstrates a racing machine's power delivery and response, with intake from front and exhaust to rear to improve air charging efficiency, and a cylinder tilted back 15 degrees to concentrate the engine’s mass, primarily to improve its stability. In order to deliver ample power into the high rpm range, the DOHC system incorporates titanium valves for both intake and exhaust (Honda patented). "The new design also offers improved air charging efficiency along with ram-air intake, thanks to the straight intake port and throttle body with 50-mm diameter bore. In shaft layout, the balancer shaft is placed above the crankshaft to make the engine shorter and concentrate the mass." Explaining details of the chassis concept, Honda said it was heavily based on the RS125R chassis. "The NSF250R’s frame is based on the RS125R’s proven unit. To optimise the rigidity in balance and torsion of a 4-stroke engine, frame specifications were determined from actual riding tests and CAE analysis. For the front engine hanger and the main pipe section, optimum balance was achieved mainly by enhancing torsional rigidity. "A newly configured swing-arm and frame body also resulted in a structure allowing smooth torsional characteristics. On the whole, stability during braking is improved, and a leeway and nimbleness during cornering exceeding those of the RS125R is ensured. The frame offers superb handling so that riders will not feel the weight increase of a 4-stroke engine, even when approaching corners." Spain’s first MotoGP world champion Alex Criville will complete demo laps on the bike during this weekend’s Catalunya Grand Prix.

NO. Honda made it clear long ago, no more 2 strokes. That what I think too. They are not sitting on lots of stock. It has all been sold. Hence the new production run.
