Loris Capirossi reckons Suzuki’s struggling factory GSV-R machine needs a radical revamp or risk a dismal 2010 MotoGP campaign.
The Japanese factory endured a torrid 2009 with Capirossi and Chris Vermeulen failing to score a single podium.
Capirossi recently tested a raft of new upgrades that included new engine parts, exhausts, top fairing and chassis in Valencia failed.
But the Italian veteran reckons Suzuki still needs to make massive improvements.
“The improvement is not enough and we are still far away. Everything together we tried in Valencia only gave us a couple of tenths. But we are still more than one second away and this is the problem,“ said Capirossi.
Suzuki’s main issue is the GSV-R doesn’t work in a wide range of conditions.
In colder conditions its chassis doesn’t generate enough heat into Bridgestone’s tyres and Capirossi said: “Our bike is too sensitive in weather conditions.
"If it is hot then we have a chance to get temperature into the tyre. But if it is cool or cold then we are in a crisis.
"The big problem is the chassis because we are not able to put enough weigh on the tyres to create any grip or traction.
"This problem existed when I joined Suzuki two years ago and we still have it.”
