How much Horsepower and Torque does a Honda ST1300 have?
The fuel-injected V4 produces a maximum horsepower of 126 hp at 8,000 rpm.
The peak torque output is 85 ft-lbs at 6,500 rpm. This provides the ST1300 with a broad, usable powerband across the rev range.
Honda ST1300 Horsepower Over the years
From 2002-2013 Honda ST1300’s Horsepower has remained at 126 hp @ 8,000 rpm.
Honda ST1300’s peak torque output has remained 85 ft-lbs at 6,500 rpm for the years 2002-2013.
Honda ST1300 Horsepower Upgrades
While stock power is strong, the ST1300 engine is highly tuneable for even more horses.
Popular mods include free-flowing air intake kits, high-flow exhaust systems, fuel controllers, and engine management chips.
These bolt-on upgrades typically add 5-10hp throughout the rev range.
More extensive modifications like big bore kits, cams, and headwork can unlock 20+hp over the stock output.
But at a certain point, chassis and tires become limiting factors in handling the power increases.
Comparison to Rivals
The Honda ST1300’s 126hp lines up closely with competitor touring bikes like the Yamaha FJR1300 at 138hp and BMW K1300GT at 127hp.
Honda ST1300’s torque output matches or exceeds rivals but produces slightly less peak power.
Real-world power feels are comparable, with the ST1300 benefiting from that V4 mid-range punch.
For pure acceleration, the heavier ST1300 can’t match lighter machines like sports bikes. But its power is well-suited to comfortable long-haul riding.

| Model | Engine | Horsepower | Torque |
| Honda ST1300 | 1,261cc V4 | 126 hp @ 8,000 rpm | 85 ft-lbs @ 6,500 rpm |
| Yamaha FJR1300 | 1,298cc Inline 4 | 142 hp @ 8,000 rpm | 103 ft-lbs @ 7,000 rpm |
| BMW R1200RT | 1,170cc Boxer Twin | 125 hp @ 7,750 rpm | 88 ft-lbs @ 6,000 rpm |
Maximizing Honda ST1300’s Horsepower
To get the most from the engine, keep the ST1300 properly maintained per the manual.
Use the best quality oil and change it regularly. Replace air filters as needed and check/adjust valve clearance.
Don’t lug the engine at extremely low rpm. Shorter gearing via aftermarket sprockets can liven up the powerband.
Adjust the riding style to keep the engine in its sweet spot between 5,000 to 8,000 rpm.
Honda ST1300’s Horsepower: Downsides
There are a few drawbacks to the ST1300’s ample power.
The engine does produce noticeable heat in slow traffic or hot climates. Fuel range is reduced compared to smaller machines.
The stock suspension may feel undersprung when riding aggressively.
As with any powerful machine, new riders should exercise extra caution when learning to manage the torque and powerband.
Real-World Power Delivery
The Honda ST1300’s 1,261cc V4 engine provides effortless, robust power delivery on the road.
ST1300’s broad torque curve offers strong acceleration from as low as 3,000 rpm, building smoothly towards the 8,000 rpm redline.
The mid-range punch makes the ST1300 feel faster than its peak horsepower suggests.
Short gearing adds to the bike’s responsive feel. The power is more than enough for spirited backroad rides or cruising at high speeds on the highway.
Conclusion
Overall, the Honda ST1300’s 126hp V4 strikes a near-perfect balance – enough grunt for an exciting ride without overwhelming newcomers to the sport-touring category.
While a potential for more power exists via modifications, even stock output is robust. Keeping the engine well-maintained and in its optimal rpm range reveals the ST1300’s performance potential for both touring and twisty roads.
