Johne Murphy (R) filled his boots late on as Leicester cut loose
Johne Murphy scored twice in injury time as Leicester romped to a convincing win away to Treviso.
He scored three tries in all, namesake Geordan Murphy also crossed and there were braces for Toby Flood and Jordan Crane as Tigers claimed a bonus point.
Flood's double and Crane's first helped the Tigers into a 17-6 half-time lead.
Treviso managed to cut the lead to a point when Benjamin de Jager went over but the Tigers ran riot in the last 30 minutes and scored six more tries.
The hosts - who took to the field in fluorescent yellow with Leicester in baby blue - fielded a multi-national line-up which included former England and Wasps centre Fraser Waters and England Sevens and former Sale winger Andy Vilk.
Treviso demonstrated from the off that they intended to play with pace and width but from the first scrum Leicester began to butcher the home pack and their forward power laid the ground work for the victory.
Italy full-back Andrea Marcato pushed an early penalty wide for the hosts before Johne Murphy sliced through in midfield, with Flood on hand to take the scoring pass and add the conversion.
The Tigers then splintered the Treviso pack at an attacking five-metre scrum as the home forwards went back as though they were on rails and Crane dotted down out wide for an unconverted try.
Marcato managed to get the hosts on the board with a brace of penalties either side of Leicester's third try, Flood crossing from Dan Hipkiss's inside pass near the right hand corner.
The England fly-half contender missed the conversion and Leicester went off the boil at the start of the second half, allowing Treviso to briefly raise the possibility of a shock home win.
After Marcato added his third penalty De Jager went over straight from the restart and the successful conversion meant Leicester only led 17-16 with half an hour to play.
But Leicester are two-time European champions and they confirmed their Heineken Cup pedigree as they dominated the last 30 minutes.
Flood edged them further ahead with a penalty and the Tigers pulled well clear with six more tries.
Johne Murphy finished off a sparkling move featuring fine passes from Geordan Murphy and Aaron Mauger before Geordan Murphy spun through two tackles to finish of a second sweeping move.
The Tigers pack confirmed their dominance by earning a penalty try before driving Crane over for his second score and Johne Murphy completed his hat-trick in injury time as Leicester won in some style.
Leicester head coach Heyneke Meyer:
"The first two games of the Heineken Cup have been a great
experience. Today's gameplan was always to start well and bring some fresh guys on in the last 20 minutes to round it off.
"In the second half, we went back to the basics, got some structure and opened it up. We did well late on and scored three or four good tries. We are improving every single week.
"As a forwards coach, I was very happy with the pushover try - you don't see pushover tries very often these days with the ELVs. It was an all-round good performance and I am very proud of the guys."
