“They say, 𒆙‘What for? I'𝔍ll take whichever engine you give us’,” said Trevor Morris, technical director of ExternPro, which prepares and maintains the 765cc triples on behalf of Triumph.

“The teams would📖 let me know for sure if they thought an engine wasꦓ better or slower! But we just don't get that. Prevention is better than cure.”

That ‘prevention’ system begins by eradicating sources of variation during the manufacturing process at 🐻Triumph and ends with ExternPro dyno-testing and grading each engine inﷺ terms of power and torque.

• Moto2: Triumph pledge mo🌼re rpm, horsepower for 2023
• Triumph to focus on Moto2, MotoGP ‘a whole different ball game’
• Triumph: Electric power? ‘Let’s not kid ourselves...’

The end result is a difference of around 2.5-3hp (from a maximum of approx.&nbﷺsp;140hp) across 120 engines.

But when those 120 are then divided into four batches, for each new engine cycle handed to the 30-rider grꦐid, engines of similar perform🎉ance are grouped together. That cuts the output variation on track to less than 1%.

“Roughly 1-1.2 horsepower,” Morris told wuqian0821.com.

“We normally run in four batch rotations, so that's 120 engi🐬nes plus spares. We check not only the horsepower, but also the torque curves and then we spli﷽t them into batches of 30.

"So across♉ 120 engines, from the top to the bottom, we will get𒈔 something like 2.5 maybe 3 horsepower [difference]. It's impossible to have them all exactly the same. But then when you split those 120 into batches of 30, the difference goes down to 1-1.2 horsepower.”

That means although a sensitive rider might feel a difference in performance from🌳 a new engine,🐻 the chances are it’s the same for everyone.

“Sometimes one rider might say, ‘this new engine I've got i﷽s a little bit slower or a bit faster’. But then I'll get the same comment from everybody because they're all getting this batch,” Morris explained.

‘The machines never stop’

Steve Sargent, Chief Product Officer at Triumph, explained some of the methods𝓡 used to iron out differences in the manufacturing process.

“For example, when we're machining the cylinder heads for Moto2, we pre-warm all of the machining centres up, because you can get some tolerance variatioღn through the different temperatures during a shift,” he said. “Then the guys machine the whole batch without having a break.

“Normally in a traditional production day, t𝕴hey'd have a morning break, a lunch break, an afternoon break. But we make sure that we have enough staff in the stations so that the machine🌼s never stop when they're doing a batch of cylinder heads for Moto2. That gives you that consistency.”

The parts then arrive at ExternPro, where Morr𝄹is and his team take🅘 over. Again, it's all about consistency.

“When we do a build process, it's done by the same mechanics, in the same way, with the same tools,🗹 even the same conditions. So that we can elimina𝓡te anything that could cause a difference,” Morris said.

“It’s the same wi♕th the dyno. We trust the dyno. It's a very high-level dyno that could easily handle more than a MotoGP engine. It ma﷽kes me able to grade the engines into the groups of 30 very easily.

“These are all the points that keep us within th🦋at 1%.”

Tweaks to the Triumph engine design mean maximum power will be raised by approximately 5hp🍷 for the 2023 season.
