If Trials 2 has given you a taste for trail bike trashing, do investigate indy motocross sim MX Simulator. Bike handling in the two-track demo is infuriating right up until the point you realise that the default 100% 'stability' setting (found in Bike Setup) is what's causing the Kawasakis and Hondas to turn like sulky supertankers. Once you've adjusted stability to a more sensible level (40% seems about right) and got into the swing of the wonderfully naturalistic lean steering (joystick recommended) the game flowers quite spectacularly.
Tim's Mostly Rather Obvious MX Simulator Demo Tips:
The lean indicator is your best friend. If it reddens don't tighten that turn any further.
After a spill you're going to want to get moving as quickly as possible, but don't throttle or turn until your leather-sheathed avatar has hoisted the bike upright.
Despite being referred to as 'robots' in the pre-race set-up screen, MX Sim's AI competitors are gloriously accident-prone. Approach blind bends and crests with caution.
For maximum chaos go for the full twenty rider field and add " --erode 1.0" to the end of the demo shortcut (this activates real-time track wear).
