MotoGP championship leader Cal Crutchlow says the new engine Honda has introduced for the 2018 season has allowed its riders to "take fewer risks".
Honda's RC213V bike has struggled on acceleration and straightline speed in the recent years, and the marque tested several engine specifications in the off-season to address its weaknesses.
The new spec was used by LCR rider Crutchlow to great effect in Argentina - as he slipstreamed past Tech3 Yamaha's Johann Zarco to win the race and take the championship lead.
"The Honda is a good bike but the engine last year was not as fast as this year," Crutchlow said after the race.
"We asked many times to make it with some more power and we got some more power.
"It makes it easier for us to be fast and be competitive. You can imagine how much we had to push in the corner last year to be competitive.
"The engine now is strong, and it makes us more competitive, all the Honda riders more competitive without taking as many risks."
Crutchlow said his Honda "murdered" Zarco's Yamaha on the back straight during his pass for victory, but did insist there was a negative point to the new engine.
