2000 KTM 640 LC4 Adventure[edit | edit source]
My KTM 640 LC4 Adventure is very vibey, even for a single. Vibration runs through your arms, legs and groin and a long ride leaves you feeling like you’ve got fizzy pop not blood running through your veins. And while the screen may look impressive it’s largely useless above 130 Km (80 mph). However, if you can ignore those whopping shortcomings the handling is extremely good thanks to the sophisticated WP shock and forks, with excellent braking courtesy of two 300 mm discs up front.
