2005 Honda VTX 1800R Overview

For 2005, Honda offers the VTX 1800R as a custom / cruiser motorcycle with 1795 cc on tap. The 2005 Honda VTX 1800R is built around a Four stroke, 52° V-twin, SOHC, 3 valves per cylinder engine, a compression ratio of 9.0:1. Out on the road, the VTX 1800R delivers 107 hp @ 5000 rpm of peak power and 163 Nm @ 3000 rpm of torque. In everyday use, the 2005 VTX 1800R tips the scales at 364.7 kg, carries a 20-litre fuel tank, offers a seat height of 696 mm and spans a 1714 mm wheelbase. That's roughly 64.1 kg heavier than the average custom / cruiser motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2005 Honda VTX 1800R spec sheet below.

2005 VTX 1800R - Pros & Cons

Strengths

  • Strong power output: Peak output on the VTX 1800R is 107 hp @ 5000 rpm and 163 Nm @ 3000 rpm of torque - strong numbers for what it is.
  • Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
  • Accessible seat height: At just 696 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.
  • Large fuel range: With a 20-litre tank, this isn't a bike you'll be stopping for fuel every hour - a real asset on longer trips.
  • Low-maintenance final drive: Shaft final drive is about as close to maintenance-free as motorcycle drivetrains get.

Considerations

  • Age-related wear: No particular mechanical concern flags for the VTX 1800R - condition on any used example comes down to how well it's been looked after.

Wear Points & Servicing Notes

Cooling system servicing

With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.

Fuelling & injector care

Fuelling on the VTX 1800R comes from PGM-FI Fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.

Brake disc and pad wear

2x 296 mm discs 3 piston calipers up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by 45mm inverted fork up front and Dual shocks with five-position spring preload adjustability at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Shaft final drive on the VTX 1800R removes chain and belt maintenance entirely - the trade-off is a little extra unsprung weight and periodic gear-oil changes.

Frame & chassis check

The Steel, Double cradle frame chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

Handling the weight at a standstill

The VTX 1800R's 364.7 kg kerb weight is worth factoring into how you handle it at a standstill - parking-lot manoeuvres need a bit more deliberate technique than on a lighter machine.

VTX 1800R - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2005 Honda VTX 1800R should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. Start it from cold if you can - a well-kept VTX 1800R settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a VTX 1800R's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Fuel system care

Injector systems like the VTX 1800R's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
