Milwaukee-Eight 117 Big Bore and Stroker Math: Displacement and Compression
What a bigger bore or longer stroke does to a 117: cubic inches, compression with the same clearance volume, and why kits change pistons.
Technical guides with the working shown: Harley-Davidson gearing, belt drive and engine math, and adventure bike tyres, lowering and suspension, with sources.
What a bigger bore or longer stroke does to a 117: cubic inches, compression with the same clearance volume, and why kits change pistons.
How a toothed final drive belt is sized, how far the axle moves when you change a pulley, and what to check before you buy.
Overall ratios to gearbox ratios, road speed in every gear, rpm at 60, 70 and 80 mph for each rear tyre, and what a pulley change does.
Same bore, stroke and compression, three claimed outputs. What differs, which 2026 models get which, and what BMEP and piston speed say.
Every version of seven mid-size adventure bikes, lowest seat first, with factory low settings, confirmed lowering kits, weights on a stated basis and sourced advice for shorter riders.
Honest pros and cons from reviews and owners, who the 450MT suits, what to budget on top of the price, and the alternatives worth a test ride.
Reviewers found the 450MT’s factory damping harsh. How to set sag and clickers solo and loaded, and when Touratech’s shock and fork kit makes sense.
The 450MT drops from 820 mm to 800 mm with a linkage bolt change. What that costs in clearance and sag, and the other ways to get your feet down.
The 450MT runs 90/90-21 and a less common 140/70-18 rear on tubeless spoked rims. Here are the sizes, the tyres we found in them, and your puncture kit.
The Ibex 450 is the North American name for the 450MT. Here is which name is used where, what is the same, and how not to confuse it with the 800MT.
