The fastes stock 48

18-11-2020 - This topic will be all about the fastes STOCK Harley Davidson Sportster 48 on the dragstrip, equipped with our stage 1 KIT.


As maybe most of you readers know, we already hold a world wide record with a Stock Buell 1125. The story can be found here:

The rider is Joe Elliot, who also owns a Harley Davidson Sportster 48. He already set a Time at Santapod Dragway just for fun with that bike and run 12.8et @ 105 mph he also won a trophy in that class.

Before the twinmotorcycles Torque Hammer full exhaust system, big sucker and ecm up date is fitted Joe took his Sportster 48 to Santa Pod Dragstrip with a V&H air filter and fuel pack whith a set of Bub slip on pipes and set a time of 12.85et @ 105 mph He will go back and see what time he can set with the Twin Motorcycles stage 1 kit for the Sportster

Joe bought our stock stage 1 Kit as we ship it world wide.

That is a kit that contains the following parts.

- Torque Hammer Full Exhaust system for Sportster

- Mastertune Software and cable kit

- We recommand to use new NGK9 sparkplugs and a set of new exhaust gaskets

In this article, you can found the complete story of the development of our Torque Hammer exhaust system for the Harley Davidson Sportsters. We start working on the Sportster after Buell shut down in 2009, to help the future Sportster rider to have a good running aircooled V-Twin motorcycle.

The conditions of this bike are:

- Normal 95-98 octane fuel

- stock engine (no modifications to gears, pulleys, cylinders, compression, cams flowing and what ever more)

- Stock Tires, Stock Pulleys

- only a airfilter, exhaust system and tune.

Let's wait and see. The bike will be running with the db-killer in, just to show what it is capable of doing in a bone stock trim.

Update 29-07-2011:

This weekend 30th april there is a MOPAR event at Santa Pod. Joe hopes he can try the sportster there.

The bike is bone stock only mounted Torque Hammer exhaust system and our famous Tune with open filter, the bike did on the first run today  1.9 60ft, 12.2 seconds on the 1/4 mile with a top speed of 109 miles an hour, perfect first results, 2 personal best in 1 run for Joe with the bike later more news.

Oke here is the old time slip with the 12.8 run, this was with the V&H fuel pack ,bub slip ons & big sucker


And here is the time slip with the 12.2 run amazing time for a stock Sportser 48 with only a exhaust, filter and Tuned ECM.


Joe's comment at the end of the day is:

Today i finaly test the Twin Motorcycles Sportster stage 1 kit, I rode the bike from Home to trhe dragstrip on pump fuel same as last time with the old set up, The conditions were the same a hot day not much air about. The 1st run was a 12.43 et @ 108 mph so a good start. I let the bike cool a little then another go a 12.27 et @ 109 mph very good ,i did a few more runs but all 12.4 et this was the hottest part of the day with poor air, I rode the bike home with no problems i even had the front wheel up on 1 run. I an very pleased with the stage 1 package compaired too the V&H fuel pack which poped and banged and the bub slip on pipes. My Sportster 48, runs strong and fast, and i did all the work at home on the bike very easy.

This new set up is worth 6 tenths of a second and about 4 mph thats amazing from a fuel map and pipe place your order now worth every £££.

After the race Joe took the bike and ride here home.
