4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Reborn in 2023 pairing the 91.8 hp 755cc Unicam twin with 21/18-inch wire-spoked wheels and 200mm Showa SFF-CA suspension; updated for 2025 with dual-projector LED styling and firmer damping.
Oil & Clutch Mechanical Engineering Note
Takes 3.6 L of SAE 10W-30 JASO MA oil with spin-on filter HF204; because the sump and exhaust collector sit low with no stock bash plate, add an aluminum skid plate before off-road trails.
Garage Wrenching Gotchas
- Both the 21-inch front and 18-inch rear wire-spoked wheels require inner tubes—tubeless plug kits will not work on a roadside flat.
- Custom User Mode settings for Rear ABS Off and low HSTC reset when the key is turned off—re-verify dash icons before dropping back onto loose gravel.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the Honda XL750 Transalp (RD16) (2023–Present) require?
Because its wet multi-plate clutch shares engine oil with the gearbox, run SAE 10W-30 (JASO MA) at 3.4 L (3.59 US qt) drain-only and 3.6 L (3.80 US qt) with filter (15410-MCJ-000 / HF204).
How do you accurately check the oil level on the XL750 Transalp (RD16), and what are its service intervals?
Hold the bike upright on level ground 2–3 minutes after shutdown, wipe the dipstick, and rest it on the filler threads without screwing it in (threading it in reads artificially high and risks oil starvation). Torque the drain plug to 30 N·m with a new crush washer. Factory oil change intervals are every 12,000 km, with valve clearance inspection every 24,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the XL750 Transalp (RD16)?
Equipped with 90/90-21M/C 54H front and 150/70R18M/C 70H rear tube-type rims (mushroom/string plugs will not seal—carry spare inner tubes), set cold tire pressures to 33 / 36 PSI (225/250 kPa) solo or 33 / 41 PSI loaded. Seat height is 850 mm (33.5 in) at 208 kg wet weight, delivering ~389 km per 16.9 L tank.
