As an entry-level motorcycle, the KTM 125 Adventure is frequently a blank page for those wishing to give their ride a bit of pizazz and improve it. That said, how much would it cost, and how labor-intensive would it be to modify the components of a $500 bike so that it offered better performance than it could on a stock, larger, more capable motorcycle? Riders argue about whether to spend money on aftermarket parts such as exhaust systems, suspension upgrades, and performance ECUs for a 125cc engine. The discussion also explores the trade-off between enhancing the bike’s capabilities and when diminishing returns on investment start to kick in. It also looks at the emotional side of customizing your first bike over the practicalities of riding goals into the future and progression onto bigger bikes.
