Really unhappy with the Gen 4 at track day yesterday. It really sucked in lower speed corners with no feel on corner entry. It just feels big and cumbersome. The ride height adjustment did help with holding the line on corner exit but there's just not enough feel to enter slower speed corners with aggression. I'm really hoping its the bridgestone tires their stock 016s. I pulled the Gen 1 from the trailer and went much faster right away. Its probably apples and oranges because the Gen 1 has Race Tech components and is using Q3s. The Gen 1 just feels and is smaller and I really enjoy the way the motor delivers power and of course it has shorter gearing. It gives great feedback on corner entry and exit. The Gen 4 was geared way to tall for the track I could go around almost all the track in second only the straight required a shift to third. My son rode it also and had similar complaints. We put it back in the trailer and finished the day on the Gen 1 that put the smile back on our face. I'm going to try some Q3s for its next outing at the track hope that's what the problem is.
