Land & Sea’s DYNOmite Motorcycle and ATV Dynamometers combine sophisticated data-acquisition electronics with DYNO-MAX™ software for affordable (inertial + steady state) horsepower testing. It is like getting two dynos in one.

“Seat of the pants’ tuning is hopeless! Rolling-road dyno testing is the only way to evaluate repairs or perform modifications on high-tech factory pro motorcycles… without leaving the garage.”

Motorcycle-only dynamometer offers the industry’s best value for serious testing. Available as an (upgradeable) inertia-only model or with integral eddy-current absorber. Custom DYNOmite V-twin motorcycle engine dynamometers… that were developed for this manufacturer’s end-of-line production testing.

Standard 800 Motorcycle/ATV Dynos include: 16"diameter x 50" wide medium inertia roll assembly – with our machined-in “traction grooves,” quick-adjust wheelbase front mount, dual roll-on ramps, tie downs, casters, roller guards, eddy-current absorber (with a step-up drive), full-bridge torque arm transducer, electronic auto-load control, DYNOmite data-acquisition computer, DYNO-MAX software, inductive RPM pickup, AC power supply, and data wiring harness. (Water-brake or AC absorbers, 50 Hp “scooter duty” models, and mobile “drag race” packages are also available.)

Low-cost 800 “Lite” Motorcycle (only) Dyno includes: 16"-diameter x 25" wide medium-inertia roll and heavy-duty welded frame assembly – with machined-in “traction grooves,” quick-adjust wheelbase front mount, roll-on ramp, motorcycle tie-downs, DYNOmite-Lite data-acquisition computer, DYNO-MAX “Lite” software, an AC power supply, and data wiring harness. (13"-diameter "scooter-duty" model available.)

DYNO-MAX™ Software option creates a full vehicle dashboard on your PC. Features include: real-time trace graph display, adjustable visual and audible limit warnings, operator configurable analog and digital gauge ranges, pushbutton controls, color graphing, test-report database, inertia compensation, Smart-Record™ trigger points, adjustable real-time data dampening, data import/export, semi-automatic torque zeroing, voice alarms, instant playback, etc. (Click for full list of features.)

DYNOmite data-acquisition computer automatically displays and records true horsepower, torque, RPM, elapsed time, MPH, etc. at up to 1,000 readings per second (per channel). It will also apply Standard, SAE, or DIN atmospheric correction factors for air temperature, barometric pressure, and humidity conditions.

Motorcycle/ATV models include dual heavy-duty drive-on ramps (roll-guards hinge for ATV testing). Wide, low-profile deck provides secure feel during big-bike runs. Many ATV models can be easily tested using the optional front-tire stop bar kit. This doubles the potential income from your motorcycle/ATV dynamometer investment.

Forget “flash acceleration smoke shows”! Absorption DYNOmites display honest unlimited Hp* using a strain-gauge torque transducer, under a controlled road load – vital for correct injection system mapping. Beware inertia-only brands with no option to hold a MPH and RPM setting, or unable to display true Hp and torque in real time. Absorber-based systems can execute step RPM tests and realistic-rate sweeps of the Hp band. They pick up longer term problems often missed during short power bursts. Because everything is done under electronic auto-load control, tests are easily run by a single mechanic.

Simulate road and track conditions by allowing DYNO-MAX’s “Road Load Simulation” mode to simulate vehicle air drag, momentum, rolling friction, etc. Just enter the bike’s weight (with rider) and drag data. After that, to the driveline and operator, the “feel” is like actually driving along the highway.

Machined-in “traction grooves” provide more traction (but less heat buildup) than cosmetic diamond-knurled rolls – without requiring excessive (Hp-robbing) strap-down force. Our chassis dynamometer assembly-line area, just before pre-shipping testing. We also accommodate production and servicing of private-label brands − with the capability to take your product line from raw material to decal application."

Dynamically balanced roll with machined-in “traction grooves” limits vibration and tire heating. Test bikes to 250 MPH and 675+ Hp* on the higher-capacity DYNOmite dyno systems. (Capacities are primarily traction dependent, so even more low-speed rear-wheel torque can be applied with tie downs.)

Avoid hazardous road tests checking out performance modifications. Instead, evaluate things like exhaust or fuel-curve changes by quickly plotting full Hp graphs. Plus, an absorber-equipped DYNOmite’s ability to hold any RPM turns mapping fuel injection, or spark curves, into “child’s play.” Forget those driveline problems that never seem to show up until you and the bike are many miles from the shop; the dyno may save you from a long hike home someday! Plus, you will avoid embarrassing comebacks and irate “Monday morning” customers.

Hand-crank adjustable wheelbase (or optional electric-actuator unit and air-clamp mount) plus two lightweight (removable) loading ramps make set-up super quick.

So easy to install you can have your DYNOmite up and running the day it arrives. You may even roll it out into the driveway for testing. Casters let you roll it into a corner when you are done. Or, add our Trailering Package (includes tires, hitch, and lights) for hauling the dyno to the races. (Engine-only dynos are also available – call.)

Affordable five-gas Exhaust-Measuring System option digitally integrates with DYNO-MAX “Pro”.

Test emissions under load using your existing (or our optional DYNOmite five-gas fully digitally integrated) exhaust analyzer. The proper emission testing procedures require repeatable absorber load control, impossible on simplistic inertia-only dynos. No more attempting to use your analyzer or AFR module during unloaded idle operation to try and verify that repaired cycles are in emission compliance. Send your customers for state inspections with confidence.

Rapid on-off setup makes it very practical to test many different model motorcycles and ATVs back to back (without doing time-consuming road trips). Just roll the machine on, strap it down, clamp on the inductive tach lead, and test. When you are done, a full color report can print out – automatically.

Make money selling dyno services. Unlike paying for repair labor hours, the same customers willingly purchase dyno time – just to get that full printed report. Selling dyno testing, to even one bike or ATV owner a day, pays off your DYNOmite in a few months!

DYNOmite Scooter Dynamometer, with powerful DYNO-MAX software, provides the industry’s best value for serious testing. Available as an (upgradeable) inertia-only model or with integral eddy-current absorber.Build customer traffic with “Dyno Days” held during open-house events. Just displaying the dynamometer in your shop helps your salespeople close new bike deals. A DYNOmite dynamometer also enhances your salespeople’s credibility, by providing them “inside info” that they can then back up – with a quick tour of your dyno cell and printed dyno sheets. Customers want to buy from shops that can demonstrate that they have the right stuff.
