Suzuki GSX-8TT (MY2025) vs Yamaha XSR900 (RN80)
Suzuki GSX-8TT vs Yamaha XSR900: two kinds of bike, and who each one is for.
Rolling on from low revs, the Suzuki GSX-8TT's twin thumps like a V-twin, and it's pulling clean well before the midrange swells. The Yamaha XSR900 revs out with years of polish behind it.
So which one do you buy?
Buy the XSR900 if…
Keeping running costs low
Gets the nod: XSR900
On running costs, the XSR900 pulls clearly ahead. It's the easier one to own on a tight budget.
The XSR900 has the edge if…
Sporty riding on twisty roads
By a nose: XSR900
In the twisties, the XSR900 asks a bit less of you to go quickly. Thank harder acceleration for that. Call it a modest edge.
What makes each one tick
GSX-8TT
Stretched over a long wheelbase, the GSX-8TT holds a corner line and doesn't twitch. Sharp edges thud through the fork. On the Blue Ridge Parkway, the quarter fairing turns the breeze aside, and there's thick padding in an upright seat. Trailing the brake lever into bends, the front settles steady.
XSR900
Halfway through an overtake or out of a mountain hairpin, the XSR900's triple hauls in whatever gear you've left it in. Corner entry on a twisting back road is where the chassis opens up, and a tight circuit doesn't faze it. At a sustained highway clip, the forward-leaning bars tuck you out of the blast. The XSR900 tracks dead straight.
Nils rode the XSR900 in Austria and Montenegro in 2024 (NastyNils Testride).
The Voice of Experience

Which one for the way you ride
Comfortable long-distance riding
Neither one fits
Hours in the saddle won't flatter either of these. They're happier on shorter runs.
A confidence-building first motorcycle
Sits this out: XSR900
No first-bike verdict for the XSR900. It's a step up for later.
They come out level on commuting. The better-kept used example is the smarter money.

Known problems to check before you buy
GSX-8TT
No confirmed faults on file yet. That's not the same as fault-free.
XSR900
- Premature rear tire wear Owners frequently report the original-equipment Bridgestone rear tire wearing out well before the mileage they expect, the soft factory sport compound squaring off and reaching the wear bars early under normal road use; a running-cost annoyance rather than a mechanical failure.
- Stalling and rough idle linked to ECU mapping Some early MY2022 and MY2023 bikes exhibit stalling at low rpm during clutch-out from stops and rough idle when warm; addressed by dealer ECU reflash under Yamaha service campaigns in several markets.
- Heat from exhaust header onto right leg Pre-cat header routing transmits noticeable heat to the rider's right thigh in slow traffic and at standstill, especially in warm weather.
- Side-stand switch fault preventing start Reports of intermittent side-stand interlock switch failures causing no-start conditions; usually resolved by switch replacement under warranty.
